The Semitic languages share a number of grammatical features, although variation — both between separate languages, and within the languages themselves — has naturally occurred over time.
Word order The reconstructed default word order in Proto-Semitic is
verb–subject–object (VSO), possessed–possessor (NG), and noun–adjective (NA). This was still the case in
Classical Arabic and
Biblical Hebrew, e.g. Classical Arabic رأى محمد فريدا ''ra'ā muħammadun farīdan
. (literally "saw Muhammad Farid", Muhammad saw Farid''). In the modern
Arabic vernaculars, however, as well as sometimes in
Modern Standard Arabic (the modern literary language based on Classical Arabic) and
Modern Hebrew, the classical VSO order has given way to SVO. Modern Ethiopian Semitic languages follow a different word order: SOV, possessor–possessed, and adjective–noun; however, the oldest attested Ethiopian Semitic language, Geʽez, was VSO, possessed–possessor, and noun–adjective. Akkadian was also predominantly SOV.
Cases in nouns and adjectives The proto-Semitic three-case system (
nominative,
accusative and
genitive) with differing vowel endings (-u, -a -i), fully preserved in Qur'anic Arabic (see
ʾIʿrab), Akkadian and
Ugaritic, has disappeared everywhere in the many colloquial forms of Semitic languages. Modern Standard Arabic maintains such case distinctions, although they are typically lost in free speech due to colloquial influence. An accusative ending
-n is preserved in Ethiopian Semitic. In the northwest, the scarcely attested
Samalian reflects a case distinction in the plural between nominative
-ū and oblique
-ī (compare the same distinction in Classical Arabic). Additionally, Semitic nouns and adjectives had a category of state, the indefinite state being expressed by
nunation.
Number in nouns Semitic languages originally had three
grammatical numbers: singular,
dual, and
plural. Classical Arabic still has a mandatory dual (i.e. it must be used in all circumstances when referring to two entities), marked on nouns, verbs, adjectives and pronouns. Many contemporary dialects of Arabic still have a dual, as in the name for the nation of Bahrain (
baħr "sea" +
-ayn "two"), although it is marked only on nouns. It also occurs in Hebrew in a few nouns (
šana means "one year",
šnatayim means "two years", and
šanim means "years"), but for those it is obligatory. The curious phenomenon of
broken pluralse.g. in Arabic,
sadd "one dam" vs.
sudūd "dams"found most profusely in the languages of Arabia and Ethiopia, may be partly of proto-Semitic origin, and partly elaborated from simpler origins.
Verb aspect and tense All Semitic languages show two quite distinct styles of morphology used for conjugating verbs.
Suffix conjugations take suffixes indicating the person, number and gender of the subject, which bear some resemblance to the pronominal suffixes used to indicate direct objects on verbs ("I saw
him") and possession on nouns ("
his dog"). So-called
prefix conjugations actually takes both prefixes and suffixes, with the prefixes primarily indicating person (and sometimes number or gender), while the suffixes (which are completely different from those used in the suffix conjugation) indicate number and gender whenever the prefix does not mark this. The prefix conjugation is noted for a particular pattern of ''
prefixes where (1) a t-
prefix is used in the singular to mark the second person and third-person feminine, while a y-'' prefix marks the third-person masculine; and (2) identical words are used for second-person masculine and third-person feminine singular. The prefix conjugation is extremely old, with clear analogues in nearly all the families of
Afroasiatic languages (i.e. at least 10,000 years old). The table on the right shows examples of the prefix and suffix conjugations in Classical Arabic, which has forms that are close to Proto-Semitic. In Proto-Semitic, as still largely reflected in East Semitic, prefix conjugations are used both for the past and the non-past, with different vocalizations. Cf. Akkadian
niprus "we decided" (preterite),
niptaras "we have decided" (perfect),
niparras "we decide" (non-past or imperfect), vs. suffix-conjugated
parsānu "we are/were/will be deciding" (stative). Some of these features, e.g.
gemination indicating the non-past/imperfect, are generally attributed to Afroasiatic. Proto-Semitic had an additional form, the
jussive, which was distinguished from the preterite only by the position of stress: the jussive had final stress while the preterite had non-final (retracted) stress. The West Semitic languages significantly reshaped the system. The most substantial changes occurred in the
Central Semitic languages (the ancestors of modern Hebrew, Arabic and Aramaic). Essentially, the old prefix-conjugated jussive or preterite became a new non-past (or imperfect), while the stative became a new past (or perfect), and the old prefix-conjugated non-past (or imperfect) with gemination was discarded. New suffixes were used to mark different moods in the non-past, e.g. Classical Arabic
-u (indicative),
-a (subjunctive), vs no suffix (jussive). It is not generally agreed whether the systems of the various Semitic languages are better interpreted in terms of tense, i.e. past vs. non-past, or aspect, i.e. perfect vs. imperfect. A special feature in classical Hebrew is the
waw-consecutive, prefixing a verb form with the letter
waw in order to change its
tense or
aspect. The
South Semitic languages show a system somewhere between the East and Central Semitic languages. Later languages show further developments. In the modern
varieties of Arabic, for example, the old mood suffixes were dropped, and new mood prefixes developed (e.g.
bi- for indicative vs. no prefix for subjunctive in many varieties). In the extreme case of Neo-Aramaic, the verb conjugations have been entirely reworked under Iranian influence.
Morphology: triliteral roots All Semitic languages exhibit a unique pattern of stems called
Semitic roots consisting typically of triliteral, or three-consonant consonantal roots (two- and four-consonant roots also exist), from which nouns, adjectives, and verbs are formed in various ways (e.g., by inserting vowels, doubling consonants, lengthening vowels or by adding prefixes, suffixes, or
infixes). For instance, the root
k-t-b (dealing with "writing" generally) yields in Arabic: :
katabtu كَتَبْتُ or كتبت "I wrote" (f and m) :
yuktab(u) يُكْتَب or يكتب "being written" (masculine) :
tuktab(u) تُكتَب or تكتب "being written" (feminine) :
yatakātabūn(a) يَتَكَاتَبُونَ or يتكاتبون "they write to each other" (masculine) :
istiktāb اِستِكتاب or استكتاب "causing to write" :
kitāb كِتَاب or كتاب "book" (the hyphen shows end of stem before various case endings) :
kutayyib كُتَيِّب or كتيب "booklet" (diminutive) :
kitābat كِتَابَة or كتابة "writing" :
kuttāb كُتاب or كتاب "writers" (broken plural) :
katabat كَتَبَة or كتبة "clerks" (broken plural) :
maktab مَكتَب or مكتب "desk" or "office" :
maktabat مَكتَبة or مكتبة "library" or "bookshop" :
maktūb مَكتوب or مكتوب "written" (participle) or "postal letter" (noun) :
katībat كَتيبة or كتيبة "squadron" or "document" :
iktitāb اِكتِتاب or اكتتاب "registration" or "contribution of funds" :
muktatib مُكتَتِب or مكتتب "subscription" and the same root in Hebrew: :
kāṯaḇti כתבתי or כָּתַבְתִּי "I wrote" :
kattāḇ כתב or כַּתָּב "reporter" (
m) :
katteḇeṯ כתבת or כַּתָּבֶת "reporter" (
f) :
kattāḇā כתבה or כַּתָּבָה "article" (plural
kattāḇōṯ כתבות) :
miḵtāḇ מכתב or מִכְתָּב "postal letter" (plural
miḵtāḇīm מכתבים) :
miḵtāḇā מכתבה "writing desk" (plural
miḵtāḇōṯ מכתבות) :
kəṯōḇeṯ כתובת "address" (plural
kəṯōḇōṯ כתובות) :
kəṯāḇ כתב "handwriting" :
kāṯūḇ כתוב "written" (
f kəṯūḇā כתובה) :
hiḵtīḇ הכתיב "he dictated" (
f hiḵtīḇā הכתיבה) :
hiṯkattēḇ התכתב "he corresponded (
f hiṯkattəḇā התכתבה) :
niḵtaḇ נכתב "it was written" (
m) :
niḵtəḇā נכתבה "it was written" (
f) :
kəṯīḇ כתיב "spelling" (
m) :
taḵtīḇ תכתיב "prescript" (
m) :
məḵuttāḇ מכותב "addressee" (
meḵutteḇeṯ מכותבת
f) :
kəṯubbā כתובה "ketubah (a Jewish marriage contract)" (
f) (Underlined consonants , , represent the
fricatives /x/, /θ/, /v/ respectively.) In Tigrinya and Amharic, this root was used widely but is now seen as an archaic form. Ethiopic-derived languages use different roots for things that have to do with writing (and in some cases counting). The primitive root
ṣ-f and the trilateral root stems
m-ṣ-f,
ṣ-h-f, and
ṣ-f-r are used. This root also exists in other Semitic languages, such as Hebrew:
sep̄er "book",
sōp̄er "scribe",
mispār "number", and
sippūr "story". This root also exists in Arabic and is used to form words with a close meaning to "writing", such as
ṣaḥāfa "journalism", and
ṣaḥīfa "newspaper" or "parchment". Verbs in other non-Semitic Afroasiatic languages show similar radical patterns, but more usually with biconsonantal roots; e.g.
Kabyle afeg means "fly!", while
affug means "flight", and
yufeg means "he flew" (compare with Hebrew, where
hap̄lēḡ means "set sail!",
hap̄lāḡā means "a sailing trip", and
hip̄līḡ means "he sailed", while the unrelated
ʕūp̄,
təʕūp̄ā, and
ʕāp̄ pertain to flight).

Cardinal numerals These are the basic numeral stems without feminine suffixes. In most older Semitic languages, the forms of the numerals from 3 to 10 exhibit
polarity of gender (also called "chiastic concord" or "reverse agreement"), i.e. if the counted noun is masculine, the numeral would be feminine and vice versa.
Typology Some early Semitic languages are speculated to have had weak
ergative features. ==Common vocabulary==
