Construct state

In Afro-Asiatic languages, the first noun in a genitive phrase that consists of a possessed noun followed by a possessor noun often takes on a special morphological form, which is termed the construct state (Latinstatus constructus). For example, in Arabic and Hebrew, the word for "queen" standing alone is malikaملكة and malkaמלכה respectively, but when the word is possessed, as in the phrase "Queen of Sheba" (literally "Sheba's Queen"; or, rather, "Queen-of Sheba"), it becomes malikat sabaʾملكة سبأ and malkat šəvaמלכת שבא respectively, in which malikat and malkat are the construct state (possessed) form and malika and malka are the absolute (unpossessed) form.

The phenomenon is particularly common in Semitic languages (such as Arabic, Hebrew, and Syriac), in Berber languages, and in the extinct Egyptian language.

In Semitic languages, nouns are placed in the construct state when they are modified by another noun in a genitive construction. That differs from the genitive case of European languages in that it is the head (modified) noun rather than the dependent (modifying) noun which is marked. However, in Semitic languages with grammatical case, such as Classical Arabic, the modifying noun in a genitive construction is placed in the genitive case in addition to marking the head noun with the construct state (compare, e.g., "John's book" where "John" is in the genitive [possessive] case and "book" cannot take definiteness marking (a, the) like in the construct state).

In some non-Semitic languages, the construct state has various additional functions besides marking the head noun of a genitive construction.

Depending on the particular language, the construct state of a noun is indicated by various phonological properties (for example, different suffixes, vowels or stress) and/or morphological properties (such as an inability to take a definite article).

In traditional grammatical terminology, the possessed noun in the construct state ("Queen") is the nomen regens ("governing noun"), and the possessor noun, often in the genitive case ("Sheba's"), is the nomen rectum ("governed noun").
