Short answers, pulled from the story.
Libyan Arabic, also called Sulaimitian Arabic by scholars, is a variety of Arabic spoken in Libya and neighboring countries. It extends into far western Egypt, where it has about one million speakers, and into Niger, where some fourteen thousand speakers as of 2024 use a related southern variety.
Libyan Arabic has two major dialect areas: an eastern variety centered on Benghazi and Bayda, and a western variety centered on Tripoli and Misrata. A distinctive southern variety also exists, centered on Sabha, and it is more closely related to the western dialect.
Two major migrations shaped Libyan Arabic: the Hilalian-Sulaimi migration and the arrival of Arabs from al-Andalus following the Reconquista. The dialect was also influenced by Greek, Italian, Turkish, and Berber, with Berber loanwords making up roughly two to three percent of its vocabulary.
Libyan Arabic is primarily a spoken dialect; Modern Standard Arabic is the normal written register in Libya. However, Libyan Arabic is used in folk poetry, cartoons, TV dramas, songs, and increasingly in internet forums, emails, and instant messaging.
Libyan Arabic has at least three clicks used interjectionally. One serves as an affirmative response and is considered casual, a dental click signals a negative response similar to the English tut, and a palatal click is used exclusively by women with a meaning close to the English word alas.
Libyan Arabic does not mark grammatical cases by declension, unlike Classical Arabic. It lacks verbal stems IV and IX entirely, and leaves stems III and X unproductive. The future tense is formed by prefixing a sound usually contracted to b onto the present tense form rather than using a separate auxiliary.
