The
grammar of Arabic has similarities with the
grammar of other Semitic languages. Some of the typical differences between Standard Arabic () and vernacular varieties are a loss of
morphological markings of
grammatical case, changes in
word order, a shift toward more
analytic morphosyntax, loss of
grammatical mood, and loss of the inflected
passive voice.
Literary Arabic As in other Semitic languages, Arabic has a complex and unusual
morphology, i.e. method of constructing words from a basic
root. Arabic has a
nonconcatenative "root-and-pattern" morphology: A root consists of a set of bare consonants (usually
three), which are fitted into a discontinuous pattern to form words. For example, the word for 'I wrote' is constructed by combining the root '''''' 'write' with the pattern '''''' 'I Xed' to form '''' 'I wrote'. Other verbs meaning 'I Xed' will typically have the same pattern but with different consonants, e.g. '''' 'I read', '''' 'I ate', '''' 'I went', although other patterns are possible, e.g. '''' 'I drank', '''' 'I said', '''' 'I spoke', where the subpattern used to signal the past tense may change but the suffix '''' is always used. From a single root '''''', numerous words can be formed by applying different patterns: • '''' 'I wrote' • '''' 'I had (something) written' • '''' 'I corresponded (with someone)' • '''' 'I dictated' • '''' 'I subscribed' • '''' 'we corresponded with each other' • '''' 'I write' • '''' 'I have (something) written' • '''' 'I correspond (with someone)' • '''' 'I dictate' • '''' 'I subscribe' • '''' 'we correspond each other' • '''' 'it was written' • '''' 'it was dictated' • '''' 'written' • '''' 'dictated' • '''' 'book' • '''' 'books' • '''' 'writer' • '''' 'writers' • '''' 'desk, office' • '''' 'library, bookshop' • etc.
Nouns and adjectives Nouns in Literary Arabic have three grammatical
cases (
nominative,
accusative, and
genitive [also used when the noun is governed by a preposition]); three
numbers (singular, dual and plural); two
genders (masculine and feminine); and three "states" (indefinite, definite, and
construct). The cases of singular nouns, other than those that end in long ā, are indicated by
suffixed short vowels (/-u/ for nominative, /-a/ for accusative, /-i/ for genitive). The feminine singular is often marked by /-at/, which is pronounced as /-ah/ before a pause. Plural is indicated either through endings (the
sound plural) or internal modification (the
broken plural). Definite nouns include all proper nouns, all nouns in "construct state" and all nouns which are
prefixed by the definite article /al-/. Indefinite singular nouns, other than those that end in long ā, add a final /-n/ to the case-marking vowels, giving /-un/, /-an/ or /-in/, which is also referred to as
nunation or
tanwīn.
Adjectives in Literary Arabic are marked for case, number, gender and state, as for nouns. The plural of all non-human nouns is always combined with a singular feminine adjective, which takes the /-at/ suffix.
Pronouns in Literary Arabic are marked for person, number and gender. There are two varieties, independent pronouns and
enclitics. Enclitic pronouns are attached to the end of a verb, noun or preposition and indicate verbal and prepositional objects or possession of nouns. The first-person singular pronoun has a different enclitic form used for verbs ( /-nī/) and for nouns or prepositions ( /-ī/ after consonants, /-ya/ after vowels). Nouns, verbs, pronouns and adjectives agree with each other in all respects. Non-human plural nouns are grammatically considered to be feminine singular. A verb in a verb-initial sentence is marked as singular regardless of its semantic number when the subject of the verb is explicitly mentioned as a noun. Numerals between three and ten show "chiasmic" agreement, in that grammatically masculine numerals have feminine marking and vice versa.
Verbs Verbs in Literary Arabic are marked for person (first, second, or third), gender, and number. They are
conjugated in two major paradigms (
past and
non-past); two
voices (active and passive); and six
moods (
indicative,
imperative,
subjunctive,
jussive, shorter
energetic and longer energetic); the fifth and sixth moods, the energetics, exist only in Classical Arabic but not in MSA. There are two
participles, active and passive, and a
verbal noun, but no
infinitive. The past and non-past paradigms are sometimes termed
perfective and
imperfective, indicating the fact that they actually represent a combination of
tense and
aspect. The moods other than the
indicative occur only in the non-past, and the
future tense is signaled by prefixing '
or ' onto the non-past. The past and non-past differ in the form of the stem (e.g., past '
vs. non-past '), and use completely different sets of affixes for indicating person, number and gender: In the past, the person, number and gender are fused into a single
suffixal morpheme, while in the non-past, a combination of
prefixes (primarily encoding person) and suffixes (primarily encoding gender and number) are used. The passive voice uses the same person/number/gender affixes but changes the vowels of the stem. The following shows a paradigm of a regular Arabic verb, '''' 'to write'. In Modern Standard, the energetic mood, in either long or short form, which has the same meaning, is almost never used.
Derivation Like other
Semitic languages, and unlike most other languages, Arabic makes much more use of
nonconcatenative morphology, applying many templates applied to roots, to
derive words than adding prefixes or suffixes to words. For verbs, a given root can occur in many different
derived verb stems, of which there are about fifteen, each with one or more characteristic meanings and each with its own templates for the past and non-past stems, active and passive participles, and verbal noun. These are referred to by Western scholars as "Form I", "Form II", and so on through "Form XV", although Forms XI to XV are rare. These stems encode grammatical functions such as the
causative,
intensive and
reflexive. Stems sharing the same root consonants represent separate verbs, albeit often semantically related, and each is the basis for its own
conjugational paradigm. As a result, these derived stems are part of the system of
derivational morphology, not part of the
inflectional system. Examples of the different verbs formed from the root '''' 'write' (using '''' 'red' for Form IX, which is limited to colors and physical defects): Form II is sometimes used to create transitive
denominative verbs (verbs built from nouns); Form V is the equivalent used for intransitive denominatives. The associated participles and verbal nouns of a verb are the primary means of forming new lexical nouns in Arabic. This is similar to the process by which, for example, the
English gerund "meeting" (similar to a verbal noun) has turned into a noun referring to a particular type of social, often work-related event where people gather together to have a "discussion" (another lexicalized verbal noun). Another fairly common means of forming nouns is through one of a limited number of patterns that can be applied directly to roots, such as the "nouns of location" in
ma- (e.g. '''' 'desk, office' < '''' 'write', '''' 'kitchen' < '''' 'cook'). The only three genuine suffixes are as follows: • The feminine suffix
-ah; variously derives terms for women from related terms for men, or more generally terms along the same lines as the corresponding masculine, e.g. '''' 'library' (also a writing-related place, but different from '''', as above). • The
nisbah suffix
-iyy-. This suffix is extremely productive, and forms adjectives meaning "related to X". It corresponds to English adjectives in
-ic, -al, -an, -y, -ist, etc. • The feminine
nisbah suffix
-iyyah. This is formed by adding the feminine suffix
-ah onto nisba adjectives to form abstract nouns. For example, from the basic root '''' 'share' can be derived the Form VIII verb '''' 'to cooperate, participate', and in turn its verbal noun '''' 'cooperation, participation' can be formed. This in turn can be made into a nisbah adjective '''' 'socialist', from which an abstract noun '''' 'socialism' can be derived. Other recent formations are '''' 'republic' (lit. "public-ness", < '''' 'multitude, general public'), and the
Gaddafi-specific variation '''' 'people's republic' (lit. "masses-ness", < '''' 'the masses', pl. of '''', as above).
Colloquial varieties The spoken dialects have lost the case distinctions and make only limited use of the dual (it occurs only on nouns and its use is no longer required in all circumstances). They have lost the mood distinctions other than imperative, but many have since gained new moods through the use of prefixes (most often /bi-/ for indicative vs. unmarked subjunctive). They have also mostly lost the indefinite "nunation" and the internal passive. The following is an example of a regular verb paradigm in Egyptian Arabic. == Writing system ==
