Sanʽani Arabic
Sanʽani Arabic is an Arabic dialect spoken in north of Yemen in the city of Sana'a. Phonology. The Sanaani dialect is distinguished among Yemeni dialects by its use of the sound in the place of the (."") used in Modern Standard Arabic. Grammar. Along with these phonological similarities to other dialects, Sanʽani Arabic also has several unique features. It uses the classical "mā" in the meaning of "what", as well as in negations. Unlike the classical usage, this "mā" is used without distinction in verbal and nominal sentences alike. Sanʽani Arabic represents the future aspect with a complex array  of prefixes, depending on the person of the verb. For first-person verbs the prefix (ša-) or (‘ad) is used. The derivation of ("ša-") is apparently related to the classical ("sa-"), and ("‘ad") is likely an abbreviation of ("ba‘d"), meaning "after". For all other persons in Sanʽa proper the simple prefix ("‘a-") is used, although many of the villages around Sanʽa extend the use of ("ša-") for all persons. Syntax. Sanʽani syntax differs from other Arabic dialects in a number of ways. It is one of few remaining Arabic dialects to retain the "mā af‘al" exclamatory sentence type with the  meaning "how (adjective)". For instance, "mā ajmal", is used to mean "how beautiful", from the adjective "jamīl", meaning "beautiful"; a construction it shares with Libyan Arabic and Levantine Arabic. Vocabulary. The Sanʽani vocabulary is also very distinct and conservative. The classical verb "sāra", "yasīr" is retained with the meaning of "to go" (similar to Moroccan). "Shalla", "yashill" is used to mean "to take/get". As an example of its distinctiveness, during an appearance of the would-be parliament speaker of Yemen, Abdullah Alahmar, on Al-Jazeera TV some years ago, viewers and the TV host needed a translation of his  Yemeni dialect into Standard Arabic in order to understand what he said.
