Influence on other languages

In addition to influencing the grammar, vocabulary and syntax of Egyptian Arabic, Coptic has lent to both Arabic and Modern Hebrew such words as:

• timsāḥ (Arabic: تمساح; Hebrew: תמסח), "crocodile"; emsah (ⲉⲙⲥⲁϩ); this subsequently entered Turkish as timsah. Coptic ⲉⲙⲥⲁϩ is grammatically masculine and hence would have taken the form pemsah (Sahidic: ⲡⲉⲙⲥⲁϩ; Bohairic: ⲡⲓⲉⲙⲥⲁϩ) with the definite articular prefix. Hence it is unclear why the word should have entered Arabic with an initial t, which would have required the word to be grammatically feminine (i.e. Sahidic: *ⲧⲉⲙⲥⲁϩ; Bohairic: *ϯⲉⲙⲥⲁϩ).
• ṭūbah, Arabic: طوبة, "brick"; Sahidic: ⲧⲱⲱⲃⲉ, tōōbe; Bohairic ⲧⲱⲃⲓ, tōbi; this subsequently entered Catalan and Spanish (via Andalusian Arabic) as tova and adobe respectively, the latter of which was borrowed by American English.
• wāḥah, Arabic: واحة, "oasis"; Sahidic: ⲟⲩⲁϩⲉ, ouahe; Bohairic: ⲟⲩⲉϩⲓ, ouehi; this subsequently entered Turkish as vaha

A few words of Coptic origin are found in the Greek language; some of the words were later lent to various European languages — such as barge, from Coptic baare (ⲃⲁⲁⲣⲉ, "small boat").

However, most words of Egyptian origin that entered into Greek and subsequently into other European languages came directly from Ancient Egyptian, often Demotic. An example is the Greek oasis (ὄασις), which comes directly from Egyptian wḥꜣt or Demotic wḥj. However, Coptic reborrowed some words of Ancient Egyptian origin into its lexicon, via Greek. For example, both Sahidic and Bohairic use the word ebenos, which was taken directly from Greek ἔβενος ("ebony"), originally from Egyptian hbnj.

Many place names in modern Egypt are Arabic adaptations of their former Coptic names:

The Coptic name ⲡⲁⲡⲛⲟⲩⲧⲉ, papnoute (from Egyptian pꜣy-pꜣ-nṯr), means "belonging to God" or "he of God".^[16][17][18] It was adapted into Arabic as Babnouda, which remains a common name among Egyptian Copts to this day. It was also borrowed into Greek as the name Παφνούτιος (Paphnutius). That, in turn, is the source of the Russian name Пафнутий (Pafnuty), perhaps best known in the name of the mathematician Pafnuty Chebyshev.

Pre-Islamic period

The earliest attempts to write the Egyptian language using the Greek alphabet are Greek transcriptions of Egyptian proper names, most of which date to the Ptolemaic Kingdom. Scholars frequently refer to this phase as pre-Coptic. However, it is clear that by the Late Period of ancient Egypt, demotic scribes regularly employed a more phonetic orthography, a testament to the increasing cultural contact between Egyptians and Greeks even before Alexander the Great's conquest of Egypt. Coptic itself, or Old Coptic, takes root in the first century. The transition from the older Egyptian scripts to the newly adapted Coptic alphabet was in part due to the decline of the traditional role played by the priestly class of ancient Egyptian religion, who, unlike most ordinary Egyptians, were literate in the temple scriptoria. Old Coptic is represented mostly by non-Christian texts such as Egyptian pagan prayers and magical and astrological papyri. Many of them served as glosses to original hieratic and demotic equivalents. The glosses may have been aimed at non-Egyptian speakers.

Under late Roman rule, Diocletian persecuted many Egyptian converts to the new Christian faith, which forced new converts to flee to the Egyptian deserts. In time, the growth of these communities generated the need to write Christian Greek instructions in the Egyptian language. The early Fathers of the Coptic Church, such as Anthony the Great, Pachomius the Great, Macarius of Egypt and Athanasius of Alexandria, who otherwise usually wrote in Greek, addressed some of their works to the Egyptian monks in Egyptian. The Egyptian language, now written in the Coptic alphabet, flourished in the second and third centuries. However, it was not until Shenoute that Coptic became a fully standardised literary language based on the Sahidic dialect. Shenouda's native Egyptian tongue and knowledge of Greek and rhetoric gave him the necessary tools to elevate Coptic, in content and style, to a literary height nearly equal to the position of the Egyptian language in ancient Egypt.

Islamic period

The Muslim conquest of Egypt by Arabs came with the spread of Islam in the seventh century. At the turn of the eighth century, Caliph Abd al-Malik ibn Marwan decreed that Arabic replace Koine Greek as the sole administrative language. Literary Coptic gradually declined, and within a few hundred years, Egyptian bishop Severus Ibn al-Muqaffaʿ found it necessary to write his History of the Patriarchs in Arabic. However, ecclesiastically the language retained an important position, and many hagiographic texts were also composed during this period. Until the 10th century, Coptic remained the spoken language of the native population outside the capital.

As a written language, Coptic is thought to have completely given way to Egyptian Arabic around the 13th century,^[20] though it seems to have survived as a spoken language until the 17th century^[2] and in some localities even longer.^[3]

The Coptic language massively declined under the hands of Fatimid Caliph Al-Hakim bi-Amr Allah, as part of his campaigns of religious persecution (which in turn targeted not only Christians and Jews but also at times the Sunni Muslim majority). He issued strict orders completely prohibiting the use of Coptic anywhere, whether in schools, public streets, and even homes, including mothers speaking to their children. Those who did not comply had their tongues cut off. He personally walked the streets of Cairo and eavesdropped on Coptic-speaking homes to find out if any family was speaking Coptic.^[21][22]

From the medieval period there is one known example of tarsh-printed Coptic. The fragmentary amulet A.Ch. 12.145, now in the Austrian National Library, contains a frame of Coptic text around an Arabic main text.^[23]

In the early 20th century, some Copts tried to revive the Coptic language, but they were unsuccessful.^[24]

In the second half of the 20th century, Pope Cyril VI of Alexandria started a national Church-sponsored movement to revive Coptic. Several works of grammar were published, including a more comprehensive dictionary than had been formerly available. The scholarly findings of the field of Egyptology and the inauguration of the Institute of Coptic Studies further contributed to the renaissance. Efforts at language revitalisation continue to be undertaken, both inside and outside the Church, and have attracted the interest of Copts and linguists in and outside of Egypt.

Vowels

There are some differences of opinion among Coptic language scholars on the correct phonetic interpretation of the writing system of Coptic. Differences centre on how to interpret the pairs of letters ⲉ/ⲏ and ⲟ/ⲱ. In the Attic dialect of Ancient Greek in the 5th century BC, the first member of each pair is a short closed vowel /e, o/, and the second member is a long open vowel /ɛː, ɔː/. In some interpretations of Coptic phonology,^[31] it is assumed that the length difference is primary, with ⲉ/ⲏ /e, eː/ and ⲟ/ⲱ is /o, oː/. Other scholars^[32][33] argue for a different analysis in which ⲉ/ⲏ and ⲟ/ⲱ are interpreted as /e, ɛ/ and /o, ɔ/.

These two charts show the two theories of Coptic vowel phonology:

Dialects vary in their realisation. The difference between [o] and [u] seems to be allophonic. Evidence is not sufficient to demonstrate that these are distinct vowels, and if they are, the difference has a very low functional load. For dialects that use orthographic <ⲉⲓ> for a single vowel, there appears to be no phonetic difference from <ⲓ>.

Double orthographic vowels are presumed here to be long, as that makes the morphology more straightforward. (Another common interpretation is that these represented glottal stop.)

There is no length distinction in final stressed position, but only those vowels that occur long appear there: <(ⲉ)ⲓ, ⲉ, ⲁ, ⲟ~ⲱ, ⲟⲩ>.

In Sahidic, the letter ⲉ was used for short /e/ before back fricatives, and also for unstressed schwa /ə/. It's possible there was also a distinction between short /ɛ/ and /a/, but if so the functional load was extremely low.

Bohairic did not have long vowels. /i/ was only written <ⲓ>. As above, it's possible that /u/ and /o/ were distinct vowels rather than just allophones.

In Late Coptic (that is, Late Bohairic), the vowels were reduced to those found in Egyptian Arabic, /a, i, u/. <ⲱ, ⲟ> became /u/, <ⲉ> became /æ/, and <ⲏ> became either /ɪ/ or /æ/. It is difficult to explain <ⲏ>. However, it generally became /æ/ in stressed monosyllables, /ɪ/ in unstressed monosyllables, and in polysyllables, /æ/ when followed by /i/, and /ɪ/ when not.

There were no doubled orthographic vowels in Mesokemic. Some representative correspondences with Sahidic are:

It is not clear if these correspondences reflect distinct pronunciations in Mesokemic, or if they are an imitation of the long Greek vowels <η, ω>.

Consonants

As with the vowels, there are differences of opinion over the correct interpretation of the Coptic consonant letters, particular the letters ϫ and ϭ. ϫ is transcribed as ⟨j⟩ in many older Coptic sources and ϭ as ⟨ɡ⟩^[31] or ⟨č⟩. Lambdin (1983) notes that the current conventional pronunciations are different from the probable ancient pronunciations: Sahidic ϫ was probably pronounced [tʲ] and ϭ was probably pronounced [kʲ]. Reintges (2004, p. 22) suggests that ϫ was pronounced [tʃ].

Beside being found in Greek loanwords, the letters ⟨φ, θ, χ⟩ were used in native words for a sequence of /p, t, k/ plus /h/, as in ⲑⲉ = ⲧ-ϩⲉ "the-way" (f.sg.) and ⲫⲟϥ = ⲡ-ϩⲟϥ "the-snake" (m.sg). The letters did not have this use in Bohairic, which used them for single sounds.

It is possible that in addition there was a glottal stop, ʔ, that was not consistently written. Coptic does not seem to have had a glottal stop at the beginning of orthographically vowel-initial words. It is possible that vowels written double were an attempt to indicate glottal stop, rather than a long vowel, in the middle of a word. However, there is little evidence for this (e.g., Arabic words with short vowels and glottal stop are not written with double vowels in Coptic, and Coptic words with double orthographic vowels are transcribed with long vowels rather than hamza in Arabic.)

In Late Coptic (ca. 14th century), Bohairic sounds that did not occur in Egyptian Arabic were lost. A possible shift from a tenuis-aspirate distinction to voiced-tenuis is only attested from the alveolars, the only place that Arabic has such a contrast.

Earlier phases of Egyptian may have contrasted voiceless and voiced bilabial plosives, but the distinction seems to have been lost. Late Egyptian, Demotic and Coptic all interchangeably use their respective graphemes to indicate either sound; for example, Coptic for 'iron' appears alternately as ⲡⲉⲛⲓⲡⲉ, ⲃⲉⲛⲓⲡⲉ and ⲃⲓⲛⲓⲃⲉ. That probably reflects dialect variation. Both letters were interchanged with ⲫ and ϥ to indicate /f/, and ⲃ was also used in many texts to indicate the bilabial approximant /w/. Coptologists believe that Coptic ⲃ was articulated as a voiced bilabial fricative [β]. In the present-day Coptic Church services, this letter is realised as /v/, but it is almost certainly a result of the pronunciation reforms instituted in the 19th century.

Whereas Old Egyptian contrasts /s/ and /z/, the two sounds appear to be in free variation in Coptic, as they were since the Middle Egyptian period. However, they are contrasted only in Greek loans; for example, native Coptic ⲁⲛⲍⲏⲃ (anzēb) and ⲁⲛⲥⲏⲃⲉ (ansēbə) 'school' are homophonous. Other consonants that sometimes appear to be either in free variation or to have different distributions across dialects are [t] and [d], [ɾ] and [l] (especially in the Fayyumic dialect, a feature of earlier Egyptian) and [k] and [ɡ], with the voiceless stop consonants being more common in Coptic words and the voiced ones in Greek borrowings. Apart from the liquid consonants, this pattern may indicate a sound change in Later Egyptian, leading to a neutralisation of voiced alveolar and velar plosives. When the voiced plosives are realised, it is usually the result of consonant voicing in proximity to /n/.

Though there is no clear evidence that Coptic had a glottal stop, different orthographic means have been posited for indicating one by those who believe that it did: with ⲁ word-initially, with ⲓ word-finally in monosyllabic words in northern dialects and ⲉ in monosyllabic words in Akhmimic and Assiutic, by reduplication of a vowel's grapheme but mostly unwritten.

A few early manuscripts have a letter ⳋ or ⳃ ç where Sahidic and Bohairic have ϣ š. and Akhmimic has ⳉ x. This sound seems to have been lost early on.

Nouns

All Coptic nouns carry grammatical gender, either masculine or feminine, usually marked through a prefixed definite article as in the Romance languages. Masculine nouns are marked with the article /pə, peː/ and feminine nouns with the article /tə, teː/^[37] in the Sahidic dialect and /pi, əp/ and /ti, ət/ in the Bohairic dialect.

Bohairic: ⲡⲓⲣⲱⲙⲓ /pəˈɾomə/ – 'the man' / ϯϫⲓϫ /təˈt͡ʃit͡ʃ/ – 'the hand'

Sahidic: ⲡⲉⲣⲱⲙⲉ /pəˈɾomə/ – 'the man' / ⲧⲉϫⲓϫ /təˈt͡ʃit͡ʃ/ – 'the hand'

The definite and indefinite articles also indicate number; however, only definite articles mark gender. Coptic has a number of broken plurals, a vestige of Older Egyptian, but in the majority of cases, the article marks number. Generally, nouns inflected for plurality end in /wə/, but there are some irregularities. The dual was another feature of earlier Egyptian that survives in Coptic in only few words, such as ⲥⲛⲁⲩ (snau) 'two'.

Words of Greek origin keep their original grammatical gender, except for neuter nouns, which become masculine in Coptic.

Possession of definite nouns is expressed with a series of possessive articles which are prefixed to the noun. These articles agree with the person, number, and gender of the possessor and the number and gender of the possessed noun. The forms of the possessive article vary according to dialect.

Pronouns

Coptic pronouns are of two kinds, dependent and independent. Independent pronouns are used when the pronoun is acting as the subject of a sentence, as the object of a verb, or with a preposition. Dependent pronouns are a series of prefixes and suffixes that can attach to verbs and other nouns. Coptic verbs can therefore be said to inflect for the person, number and gender of the subject and the object: a pronominal prefix marks the subject, and a pronominal suffix marks the object, e.g. "I I'have'it the ball." When (as in this case) the subject is a pronoun, it normally is not also expressed independently, unless for emphasis.

As in other Afroasiatic languages, gender of pronouns differ only in the second and third person singular. The following table shows the pronouns of the Bohairic dialect:

Adjectives

Most Coptic adjectives are actually nouns that have the attributive particle n to make them adjectival. In all stages of Egyptian, this morpheme is also used to express the genitive; for example, the Bohairic word for 'Egyptian', ⲣⲉⲙⲛ̀ⲭⲏⲙⲓ /remənkʰeːmə/, is a combination of the nominal prefix ⲣⲉⲙ- rem- (the reduced form of ⲣⲱⲙⲓ rōmi 'man'), followed by the genitive morpheme ⲛ̀ ən ('of') and finally the word for Egypt, ⲭⲏⲙⲓ kʰēmi.

Verbs

Prepositions

Coptic has prepositions, rather than postpositions:

ϩⲓ ⲡ̀ϫⲟⲓ – hi pjoi

Pronominal objects of prepositions are indicated with enclitic pronouns:

ⲉⲣⲟⲕ – erok

ⲛⲁⲛ – nan

Many prepositions have different forms before the enclitic pronouns.^[41] Compare

ⲉ̀ⲡ̀ϫⲟⲓ – e-p-joi

ⲉⲣⲟϥ – erof

Sentential syntax

Coptic typically shows subject–verb–object (SVO) word order, as in the following examples:^[42]

Ⲁ ⲧⲉϭⲁⲙⲁⲩⲗⲉ ⲙⲓⲥⲉ ⲛ̀ⲟⲩϣⲏⲣⲉ ⲛ̀ϣⲓⲙⲉ – A tecamaule mise ənoušēre ənšime

Ⲡⲉϫⲟⲉⲓⲥ ⲛⲁⲕⲣⲓⲛⲉ ⲛ̀ⲛⲉⲗⲁⲟⲥ – Pejoeis nakrine ənnelaos

Ⲁⲓϭⲓⲛⲉ ⲙ̀ⲡⲁⲉⲓⲱⲧ – Aicine əmpaeiōt

The verbs in these sentences are in the absolute state grade,^[43] which requires that its direct object be introduced with the preposition /ən, əm/. This preposition functions like accusative case.

There is also an alternative nominal state grade of the verb in which the direct object of the verb follows with no preposition:

Ⲁⲓϭⲉⲛ ⲡⲁⲉⲓⲱⲧ – Aicen paeiōt

Upper Egypt

Sahidic

Sahidic (also known as Thebaic) is the dialect in which most known Coptic texts are written, and was the leading dialect in the pre-Islamic period. It is thought to have originally been a regional dialect from the area around Hermopolis (Coptic: Ϣⲙⲟⲩⲛⲉⲓⲛ, romanized: Shmounein). Around 300 it began to be written in literary form, including translations of major portions of the Bible (see Coptic versions of the Bible). By the 6th century, a standardised spelling had been attained throughout Egypt. Almost all native authors wrote in this dialect of Coptic. Sahidic was, beginning in the 9th century, challenged by Bohairic, but is attested as late as the 14th.

While texts in other Coptic dialects are primarily translations of Greek literary and religious texts, Sahidic is the only dialect with a considerable body of original literature and non-literary texts. Because Sahidic shares most of its features with other dialects of Coptic with few peculiarities specific to itself, and has an extensive corpus of known texts, it is generally the dialect studied by learners of Coptic, particularly by scholars outside of the Coptic Church.
