138-742: A literary language , and was also the language of the New Kingdom administration. Texts written wholly in Late Egyptian date to the Twentieth Dynasty of Egypt and later. Late Egyptian is represented by a large body of religious and secular literature , comprising such examples as the Story of Wenamun , the love poems of the Chester–Beatty I papyrus, and the Instruction of Any . Instructions became
207-566: A synthetic language , Egyptian by the Late Egyptian phase had become an analytic language . The relationship between Middle Egyptian and Late Egyptian has been described as being similar to that between Latin and Italian. The Late Egyptian stage is taken to have ended around the 8th century BC, giving rise to Demotic. Demotic is a later development of the Egyptian language written in the Demotic script , following Late Egyptian and preceding Coptic ,
276-440: A coating for many cheeses , and to waterproof leather and fabric. Wax has been used since antiquity as a temporary, removable model in lost-wax casting of gold , silver and other materials. Wax with colorful pigments added has been used as a medium in encaustic painting , and is used today in the manufacture of crayons , china markers and colored pencils . Carbon paper , used for making duplicate typewritten documents
345-573: A detailed guide to fighting Apep, referred to as The Books of Overthrowing Apep (or the Book of Apophis , in Greek). The chapters described a gradual process of dishonoring, dismemberment, and disposal, which include: In addition to stories about Re's victories, this guide had instructions for making wax models, or small drawings, of the serpent, which would be spat on, mutilated and burnt, whilst reciting spells that would aid Re in killing Apep. Fearing that even
414-1087: A diverse class of organic compounds that are lipophilic , malleable solids near ambient temperatures. They include higher alkanes and lipids , typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane , benzene and chloroform . Natural waxes of different types are produced by plants and animals and occur in petroleum . Waxes are organic compounds that characteristically consist of long aliphatic alkyl chains, although aromatic compounds may also be present. Natural waxes may contain unsaturated bonds and include various functional groups such as fatty acids , primary and secondary alcohols , ketones , aldehydes and fatty acid esters . Synthetic waxes often consist of homologous series of long-chain aliphatic hydrocarbons ( alkanes or paraffins) that lack functional groups . Waxes are synthesized by many plants and animals. Those of animal origin typically consist of wax esters derived from
483-550: A few have survived that were written in hieratic and (later) demotic. There was also a form of cursive hieroglyphs , used for religious documents on papyrus, such as the Book of the Dead of the Twentieth Dynasty ; it was simpler to write than the hieroglyphs in stone inscriptions, but it was not as cursive as hieratic and lacked the wide use of ligatures . Additionally, there was a variety of stone-cut hieratic, known as "lapidary hieratic". In
552-488: A few specialists in the language. For all other purposes, the Egyptological pronunciation is used, but it often bears little resemblance to what is known of how Egyptian was pronounced. The following consonants are reconstructed for Archaic (before 2600 BC) and Old Egyptian (2686–2181 BC), with IPA equivalents in square brackets if they differ from the usual transcription scheme: / l / has no independent representation in
621-431: A flash point >500 °F (>260 °C). Many polyethylene resin plants produce a low molecular weight stream often referred to as low polymer wax (LPW). LPW is unrefined and contains volatile oligomers, corrosive catalyst and may contain other foreign material and water. Refining of LPW to produce a polyethylene wax involves removal of oligomers and hazardous catalyst. Proper refining of LPW to produce polyethylene wax
690-495: A number of rituals and superstitions that were thought to ward off Apep, and aid Re in continuing his journey across the sky. In an annual rite called the Ritual of Overthrowing Apophis , priests would build an effigy of Apep that was thought to contain all of the evil and darkness in Egypt , and burn it to protect everyone from Apep's evil for another year. The Egyptian priests had
759-442: A popular literary genre of the New Kingdom, which took the form of advice on proper behavior. Late Egyptian was also the language of New Kingdom administration. Late Egyptian is not completely distinct from Middle Egyptian, as many "classicisms" appear in historical and literary documents of this phase. However, the difference between Middle and Late Egyptian is greater than the difference between Middle and Old Egyptian. Originally

Recently, some evidence of internal dialects has been found in pairs of similar words in Egyptian that, based on similarities with later dialects of Coptic, may be derived from northern and southern dialects of Egyptian. Written Coptic has five major dialects, which differ mainly in graphic conventions, most notably
897-432: A significant fraction of petroleum. They are refined by vacuum distillation . Paraffin waxes are mixtures of saturated n- and iso- alkanes , naphthenes , and alkyl - and naphthene-substituted aromatic compounds. A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula C n H 2 n +2 , such as hentriacontane , C 31 H 64 . The degree of branching has an important influence on

In Middle Egyptian (2055–1650 BC), a number of consonantal shifts take place. By the beginning of the Middle Kingdom period, / z / and / s / had merged, and
1035-502: A stressed vowel in syllables that had been closed in earlier Egyptian (compare ⲛⲟⲩⲃ < */ˈnaːbaw/ 'gold' and ⲧⲁⲡ < * /dib/ 'horn'). The phonemes /d g z/ occur only in Greek loanwords, with rare exceptions triggered by a nearby /n/ : ⲁⲛⲍⲏⲃⲉ/ⲁⲛⲥⲏⲃⲉ < ꜥ.t n.t sbꜣ.w 'school'. Earlier *d ḏ g q are preserved as ejective t' c' k' k ' before vowels in Coptic. Although
1104-634: A transliteration of the corresponding Demotic "alphabetical" sign(s) in angle brackets ⟨ ⟩ . More changes occur in the 1st millennium BC and the first centuries AD, leading to Coptic (1st or 3rd – c. 19th centuries AD). In Sahidic ẖ ḫ ḥ had merged into ϣ š (most often from ḫ ) and ϩ / h / (most often ẖ ḥ ). Bohairic and Akhmimic are more conservative and have a velar fricative / x / ( ϧ in Bohairic, ⳉ in Akhmimic). Pharyngeal *ꜥ had merged into glottal / ʔ / after it had affected
1173-461: A uniliteral hieroglyph. Egyptian scholar Gamal Mokhtar noted that the inventory of hieroglyphic symbols derived from "fauna and flora used in the signs [which] are essentially African", reflecting the local wildlife of North Africa, the Levant and southern Mediterranean. In "regards to writing, we have seen that a purely Nilotic, hence [North] African origin not only is not excluded, but probably reflects
1242-414: A variety of fatty acids and carboxylic alcohols. In waxes of plant origin, characteristic mixtures of unesterified hydrocarbons may predominate over esters. The composition depends not only on species, but also on geographic location of the organism. The best-known animal wax is beeswax , used in constructing the honeycombs of beehives, but other insects also secrete waxes. A major component of beeswax
1311-924: Is a fossilized wax extracted from coal and lignite . It is very hard, reflecting the high concentration of saturated fatty acids and alcohols. Although dark brown and odorous, they can be purified and bleached to give commercially useful products. As of 1995 , about 200 million kilograms of polyethylene waxes were consumed annually. Polyethylene waxes are manufactured by one of three methods: Each production technique generates products with slightly different properties. Key properties of low molecular weight polyethylene waxes are viscosity, density and melt point. Polyethylene waxes produced by means of degradation or recovery from polyethylene resin streams contain very low molecular weight materials that must be removed to prevent volatilization and potential fire hazards during use. Polyethylene waxes manufactured by this method are usually stripped of low molecular weight fractions to yield
1380-416: Is believed to be Apep. The few descriptions of Apep's origin in myth usually demonstrate that it was born after Re, usually from his umbilical cord . Geraldine Pinch claims that a much later creation myth explained that, "Apophis sprang from the saliva of the goddess Neith when she was still in the primeval waters. Her spit became a snake 120 yards long." But Apep was commonly believed to have existed from
1449-470: Is dated from the oldest known complete sentence, including a finite verb , which has been found. Discovered in the tomb of Seth-Peribsen (dated c. 2690 BC ), the seal impression reads: Extensive texts appear from about 2600 BC. An early example is the Diary of Merer . The Pyramid Texts are the largest body of literature written in this phase of the language. One of its distinguishing characteristics

Waxes are mainly consumed industrially as components of complex formulations, often for coatings. The main use of polyethylene and polypropylene waxes is in the formulation of colourants for plastics. Waxes confer matting effects (i.e., to confer non-glossy finishes) and wear resistance to paints. Polyethylene waxes are incorporated into inks in
1587-859: Is frequently used as a lubricant on drawer slides where wood to wood contact occurs. Sealing wax was used to close important documents in the Middle Ages . Wax tablets were used as writing surfaces. There were different types of wax in the Middle Ages, namely four kinds of wax ( Ragusan , Montenegro , Byzantine , and Bulgarian ), "ordinary" waxes from Spain , Poland , and Riga , unrefined waxes and colored waxes (red, white, and green). Waxes are used to make waxed paper , impregnating and coating paper and card to waterproof it or make it resistant to staining, or to modify its surface properties. Waxes are also used in shoe polishes , wood polishes , and automotive polishes, as mold release agents in mold making , as

Spermaceti occurs in large amounts in the head oil of the sperm whale . One of its main constituents is cetyl palmitate , another ester of a fatty acid and a fatty alcohol . Lanolin is a wax obtained from wool, consisting of esters of sterols . Plants secrete waxes into and on
1725-449: Is not a contrastive feature; all obstruents are voiceless and all sonorants are voiced. Stops may be either aspirated or tenuis (unaspirated), although there is evidence that aspirates merged with their tenuis counterparts in certain environments. The following table presents the consonants of Demotic Egyptian. The reconstructed value of a phoneme is given in IPA transcription, followed by
1794-399: Is sometimes reserved for the earliest use of hieroglyphs, from the late fourth through the early third millennia BC. At the earliest stage, around 3300 BC, hieroglyphs were not a fully developed writing system , being at a transitional stage of proto-writing ; over the time leading up to the 27th century BC, grammatical features such as nisba formation can be seen to occur. Old Egyptian
1863-424: Is the best-documented variety of the language, and has attracted the most attention by far from Egyptology . While most Middle Egyptian is seen written on monuments by hieroglyphs, it was also written using a cursive variant , and the related hieratic . Middle Egyptian first became available to modern scholarship with the decipherment of hieroglyphs in the early 19th century. The first grammar of Middle Egyptian
1932-406: Is the tripling of ideograms , phonograms, and determinatives to indicate the plural. Overall, it does not differ significantly from Middle Egyptian, the classical stage of the language, though it is based on a different dialect. In the period of the 3rd dynasty ( c. 2650 – c. 2575 BC ), many of the principles of hieroglyphic writing were regularized. From that time on, until
2001-551: The Coptic Catholic Church . Most hieroglyphic Egyptian texts are written in a literary prestige register rather than the vernacular speech variety of their author. As a result, dialectical differences are not apparent in written Egyptian until the adoption of the Coptic alphabet . Nevertheless, it is clear that these differences existed before the Coptic period. In one Late Egyptian letter (dated c. 1200 BC ),
2070-590: The Tenth region of the Night . The wide range of Apep's possible locations gained him the title World-Encircler . It was thought that his terrifying roar would cause the underworld to rumble. Myths sometimes say that Apep was trapped there, because he had been the previous chief god overthrown by Re, or because he was evil and had been imprisoned. The Coffin Texts imply that Apep used a magical gaze to overwhelm Re and his entourage. Re
2139-573: The hieroglyphic and hieratic scripts. Demotic is the name of the script derived from the hieratic beginning in the 7th century BC. The Coptic alphabet was derived from the Greek alphabet , with adaptations for Egyptian phonology. It was first developed in the Ptolemaic period , and gradually replaced the Demotic script in about the 4th to 5th centuries of the Christian era. The term "Archaic Egyptian"

2208-574: The liturgical language of the Coptic Church . The Egyptian language branch belongs to the Afroasiatic language family . Among the typological features of Egyptian that are typically Afroasiatic are its fusional morphology, nonconcatenative morphology , a series of emphatic consonants , a three-vowel system /a i u/ , a nominal feminine suffix * -at , a nominal prefix m- , an adjectival suffix -ī and characteristic personal verbal affixes. Of

Presented on a Naqada I (c. 4000–3550 BCE) C-ware bowl (now in Cairo) a snake was painted on the inside rim combined with other desert and aquatic animals as an enemy of a deity, seemingly a solar deity, who is invisibly hunting in a big rowing vessel. The snake on the inside rim
2484-592: The Semitic preference for triradical roots. Egyptian is probably more conservative, and Semitic likely underwent later regularizations converting roots into the triradical pattern. Although Egyptian is the oldest Afroasiatic language documented in written form, its morphological repertoire is very different from that of the rest of the Afroasiatic languages in general, and Semitic languages in particular. There are multiple possibilities: perhaps Egyptian had already undergone radical changes from Proto-Afroasiatic before it
2553-494: The beginning of time in the waters of Nu of primeval chaos. Tales of Apep's battles against Re were elaborated during the New Kingdom . Storytellers said that every day Apep must lie below the horizon and not persist in the mortal kingdom. This appropriately made him a part of the underworld . In some stories, Apep waited for Re in a western mountain called Manu , where the sun set, and in others, Apep lurked just before dawn, in

It is known today from a large corpus of surviving texts, which were made accessible to
2691-465: The cognate sets between Egyptian and Afroasiatic, the traditional theory and the neuere Komparatistik , founded by Semiticist Otto Rössler. According to the neuere Komparatistik , in Egyptian, the Proto-Afroasiatic voiced consonants */d z ð/ developed into pharyngeal ⟨ꜥ⟩ /ʕ/ : Egyptian ꜥr.t 'portal', Semitic dalt 'door'. The traditional theory instead disputes
2760-604: The definite article ⲡ is unaspirated when the next word begins with a glottal stop: Bohairic ⲡ + ⲱⲡ > ⲡⲱⲡ 'the account'. The consonant system of Coptic is as follows: Here is the vowel system reconstructed for earlier Egyptian: Vowels are always short in unstressed syllables ( ⟨tpj⟩ = */taˈpij/ 'first') and long in open stressed syllables ( ⟨rmṯ⟩ = */ˈraːmac/ 'man'), but they can be either short or long in closed stressed syllables ( ⟨jnn⟩ = */jaˈnan/ 'we', ⟨mn⟩ = */maːn/ 'to stay'). Wax Waxes are

Early research had assumed that the opposition in stops was one of voicing, but it is now thought to be either one of tenuis and emphatic consonants , as in many Semitic languages, or one of aspirated and ejective consonants , as in many Cushitic languages . Since vowels were not written until Coptic, reconstructions of the Egyptian vowel system are much more uncertain and rely mainly on evidence from Coptic and records of Egyptian words, especially proper nouns, in other languages/writing systems. The actual pronunciations reconstructed by such means are used only by

The most important source of information about Demotic phonology is Coptic. The consonant inventory of Demotic can be reconstructed on the basis of evidence from the Coptic dialects. Demotic orthography is relatively opaque . The Demotic "alphabetical" signs are mostly inherited from
2967-532: The first known Coptic text, still pagan ( Old Coptic ), from the 1st century AD. Coptic survived into the medieval period, but by the 16th century was dwindling rapidly due to the persecution of Coptic Christians under the Mamluks . It probably survived in the Egyptian countryside as a spoken language for several centuries after that. Coptic survives as the liturgical language of the Coptic Orthodox Church and
3036-493: The form of dispersions to decrease friction. They are employed as release agents , find use as slip agents in furniture, and confer corrosion resistance. Waxes such as paraffin wax or beeswax , and hard fats such as tallow are used to make candles , used for lighting and decoration. Another fuel type used in candle manufacturing includes soy . Soy wax is made by the hydrogenation process using soybean oil. Waxes are used as finishes and coatings for wood products. Beeswax
3105-655: The graphemes ⟨s⟩ and ⟨z⟩ are used interchangeably. In addition, / j / had become / ʔ / word-initially in an unstressed syllable (⟨ jwn ⟩ /jaˈwin/ > */ʔaˈwin/ "colour") and after a stressed vowel ( ⟨ḥjpw⟩ */ˈħujpVw/ > /ˈħeʔp(Vw)/ '[the god] Apis'). In Late Egyptian (1069–700 BC), the phonemes d ḏ g gradually merge with their counterparts t ṯ k ( ⟨dbn⟩ */ˈdiːban/ > Akkadian transcription ti-ba-an 'dbn-weight'). Also, ṯ ḏ often become /t d/ , but they are retained in many lexemes ; ꜣ becomes / ʔ / ; and /t r j w/ become / ʔ / at
3174-435: The hieroglyphic orthography, and it is frequently written as if it were / n / or / r / . That is probably because the standard for written Egyptian is based on a dialect in which / l / had merged with other sonorants. Also, the rare cases of / ʔ / occurring are not represented. The phoneme / j / is written as ⟨ j ⟩ in the initial position (⟨ jt ⟩ = */ˈjaːtVj/ 'father') and immediately after
3243-519: The hieroglyphic script, and due to historical sound changes they do not always map neatly onto Demotic phonemes . However, the Demotic script does feature certain orthographic innovations, such as the use of the sign h̭ for / ç /, which allow it to represent sounds that were not present in earlier forms of Egyptian. The Demotic consonants can be divided into two primary classes: obstruents ( stops , affricates and fricatives ) and sonorants ( approximants , nasals , and semivowels ). Voice
3312-409: The image of Apep could give power to the demon, any rendering would always include another deity to subdue the monster. As Apep was thought to live in the underworld, he was sometimes thought of as an Eater of Souls . Thus the dead also needed protection, so they were sometimes buried with spells that could destroy Apep. The Book of the Dead does not frequently describe occasions when Re defeated
3381-464: The language's final stage of development, the Coptic alphabet replaced the older writing system. Hieroglyphs are employed in two ways in Egyptian texts: as ideograms to represent the idea depicted by the pictures and, more commonly, as phonograms to represent their phonetic value. As the phonetic realization of Egyptian cannot be known with certainty, Egyptologists use a system of transliteration to denote each sound that could be represented by
3450-406: The latter of which it shares much with. In the earlier stages of Demotic, such as those texts written in the early Demotic script, it probably represented the spoken idiom of the time. However, as its use became increasingly confined to literary and religious purposes, the written language diverged more and more from the spoken form, leading to significant diglossia between the late Demotic texts and
3519-403: The modern world following the decipherment of the ancient Egyptian scripts in the early 19th century. Egyptian is one of the earliest known written languages , first recorded in the hieroglyphic script in the late 4th millennium BC . It is also the longest-attested human language, with a written record spanning over 4,000 years. Its classical form, known as " Middle Egyptian ," served as

Millions of tons of paraffin waxes are produced annually. They are used in foods (such as chewing gum and cheese wrapping), in candles and cosmetics, as non-stick and waterproofing coatings and in polishes. Montan wax
3726-503: The quality of the surrounding vowels. / ʔ / is not indicated orthographically unless it follows a stressed vowel; then, it is marked by doubling the vowel letter (except in Bohairic): Akhmimic ⳉⲟⲟⲡ /xoʔp/ , Sahidic and Lycopolitan ϣⲟⲟⲡ šoʔp , Bohairic ϣⲟⲡ šoʔp 'to be' < ḫpr.w * /ˈχapraw/ 'has become'. The phoneme ⲃ / b / was probably pronounced as a fricative [ β ] , becoming ⲡ / p / after
3795-861: The reality" that the geographical location of Egypt is, of course, in Africa. While the consonantal phonology of the Egyptian language may be reconstructed, the exact phonetics is unknown, and there are varying opinions on how to classify the individual phonemes. In addition, because Egyptian is recorded over a full 2,000 years, the Archaic and Late stages being separated by the amount of time that separates Old Latin from Modern Italian , significant phonetic changes must have occurred during that lengthy time frame. Phonologically, Egyptian contrasted labial, alveolar, palatal, velar, uvular, pharyngeal, and glottal consonants. Egyptian also contrasted voiceless and emphatic consonants, as with other Afroasiatic languages, but exactly how
3864-599: The same graphemes are used for the pulmonic stops ( ⟨ ⲧ ϫ ⲕ ⟩ ), the existence of the former may be inferred because the stops ⟨ ⲡ ⲧ ϫ ⲕ ⟩ /p t c k/ are allophonically aspirated [pʰ tʰ cʰ kʰ] before stressed vowels and sonorant consonants. In Bohairic, the allophones are written with the special graphemes ⟨ ⲫ ⲑ ϭ ⲭ ⟩ , but other dialects did not mark aspiration: Sahidic ⲡⲣⲏ , Bohairic ⲫⲣⲏ 'the sun'. Thus, Bohairic does not mark aspiration for reflexes of older *d ḏ g q : Sahidic and Bohairic ⲧⲁⲡ */dib/ 'horn'. Also,

Even the number of signs used remained constant at about 700 for more than 2,000 years. Middle Egyptian was spoken for about 700 years, beginning around 2000 BC, during the Middle Kingdom and the subsequent Second Intermediate Period .

Middle Egyptian has been well-understood since then, although certain points of the verbal inflection remained open to revision until the mid-20th century, notably due to the contributions of Hans Jakob Polotsky . The Middle Egyptian stage is taken to have ended around the 14th century BC, giving rise to Late Egyptian. This transition
