Coptic is primarily a
fusional (inflectional) language, though some scholars, such as , have suggested it has
agglutinative or even polysynthetic tendencies. Its morphology relies heavily on prefixation and
clitics, but these forms frequently encode multiple grammatical functions. Its standard word order is
subject–verb–object, though it can shift to
verb–subject–object with the appropriate preposition before the subject. Number, gender, tense, and mood are marked by prefixes and clitics, which evolved from
Late Egyptian. While earlier stages of Egyptian used suffixation for verb conjugation, Coptic largely replaced these with periphrastic constructions and prefix-based inflection, though vestiges of suffix inflection survive in certain verbs and possessive structures. For example, the
Middle Egyptian form
*satāpafa ('he chooses', written
stp.f in hieroglyphs) corresponds to the Coptic (Sahidic)
f.sotp (, 'he chooses'), where the prefix "f-" encodes multiple grammatical functions simultaneously, characteristic of fusional morphology rather than agglutination.
Nouns All Coptic nouns carry
grammatical gender, either masculine or feminine, usually marked through a definite article as in the
Romance languages, though Coptic articles are prefixes rather than separate words. Masculine nouns are marked with the article and feminine nouns with the article in the Sahidic dialect and and in the Bohairic dialect. : Bohairic: – 'the man' / – 'the hand' : Sahidic: – 'the man' / – '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 , but there are some irregularities. The dual was another feature of earlier Egyptian that survives in Coptic in only few words, such as (
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.
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', , is a combination of the nominal prefix
rem- (the reduced form of
rōmi 'man'), followed by the genitive morpheme
ən ('of') and finally the word for Egypt,
kʰēmi.
Verbs Verbal grade system Coptic, like Ancient Egyptian and Semitic languages, has root-and-pattern or templatic morphology, and the basic meaning of a verb is contained in a root and various derived forms of root are obtained by varying the vowel pattern. For example, the root for 'build' is
kt. It has four derived forms: • (the absolute state grade) • ket- (the nominal state grade) • kot= (the pronominal state grade) • (the stative grade) (The nominal state grade is also called the construct state in some grammars of Coptic.) The absolute, nominal, and pronominal state grades are used in different syntactic contexts. The absolute state grade of a transitive verb is used before a direct object with the accusative preposition , and the nominal state grade is used before a direct object with no case-marking. The pronominal state grade is used before a pronominal direct object enclitic. In addition, many verbs also have a neutral state grade, used to express a state resulting from the action of the verb. Compare the following forms: ABS:absolute state grade NOM:nominal state grade PRONOM:pronominal state grade {{fs interlinear |lang=cop |indent=2 |italics3=yes |glossing4=yes {{fs interlinear |lang=cop |indent=2 |italics3=yes |glossing4=yes {{fs interlinear |lang=cop |indent=2 |italics3=yes |glossing4=yes For most transitive verbs, both absolute and nominal state grade verbs are available for non-pronominal objects. However, there is one important restriction, known as ''Jernstedt's rule
(or the Stern-Jernstedt rule'') : present-tense sentences cannot be used in the nominal state grade. Thus sentences in the present tense always show a pattern like the first example above (absolute state), never the second pattern (nominal state). In general, the four grades of Coptic verb are not predictable from the root, and are listed in the lexicon for each verb. The following chart shows some typical patterns of correspondence: It is hazardous to make firm generalisations about the relationships between these grade forms, but the nominal state is usually shorter than the corresponding absolute and neutral forms. Absolute and neutral state forms are usually bisyllabic or contain a long vowel; the corresponding nominal state forms are monosyllabic or have short vowels.
Tense/aspect/mood inflection Coptic has a very large number of distinct
tense-aspect-mood categories, expressed by particles which are either before the verb or before the subject. The future is a preverbal particle and follows the subject: {{fs interlinear |lang=cop |indent=2 |italics3=yes |glossing4=yes In contrast, the perfective is a pre-subject particle: {{fs interlinear |lang=cop |indent=2 |italics3=yes |glossing4=yes There is some variation in the labels for the tense/aspect/mood categories. The chart below shows the labels from , , . (Where they agree, only one label is shown.) Each form lists the morphology found with a nonpronominal subject (Marked with an underscore in Coptic) and a third person singular masculine pronominal subject ('he'): An approximate range of use for most of the tense/aspect/mood categories is shown in the following table:
Second tenses An unusual feature of Coptic is the extensive use of a set of "second tenses", which are required in certain syntactic contexts. "Second tenses" are also called "relative tenses" in some work.
Prepositions Coptic has prepositions, rather than postpositions: {{fs interlinear |lang=cop |indent=2 |italics3=yes |glossing4=yes Pronominal objects of prepositions are indicated with enclitic pronouns: {{fs interlinear|indent=2|ipa2=yes {{fs interlinear|indent=2|ipa2=yes Many prepositions have different forms before the enclitic pronouns.
