Algerian Arabic  Algerian Arabic (known as Darja in Algeria) is a dialect derived from the form of Arabic spoken in northern Algeria. It belongs to the Maghrebi Arabic language continuum and is partially mutually intelligible with Tunisian and Moroccan. Like other varieties of Maghrebi Arabic, Algerian has a mostly Semitic vocabulary. It contains Berber and Latin (African Romance) influences and has numerous loanwords from French, Andalusian Arabic, Ottoman Turkish and Spanish. Algerian Arabic is the native dialect of 75% to 80% of Algerians and is mastered by 85% to 100% of them. It is a spoken language used in daily communication and entertainment, while Modern Standard Arabic (MSA) is generally reserved for official use and education. The Algerian language includes several distinct dialects belonging to two genetically different groups: pre-Hilalian and Hilalian dialects. Hilalian dialects of Algeria belong to three linguistic groups:  Modern koine languages, urban and national, are based mainly on Hilalian dialects. Pre-Hilalian Arabic dialects are generally classified into three types: Urban, "Village" Sedentary, and Jewish dialects. Several Pre-Hilalian dialects are spoken in Algeria:  In comparison to other Maghrebi dialects, Algerian Arabic has retained numerous phonetic elements of Classical Arabic lost by its relatives; In Algiers dialect, the letters 􏰣􏰄 and ث 􏰝􏰌are not used, they are in most cases pronounced as the graphemes and ت respectively. This conservatism concerning pronunciation is in contrast to Algerian Arabic grammar which has shifted noticeably. In terms of differences from Classical Arabic, the previous /r/ and /z/ phonemes have developed contrastive glottalized forms and split into /r/ and /rˤ/; and /z/ and /zˤ/. Additionally /q/ from Classical Arabic has split into /q/ and /g/ in most dialects. The phonemes /v/ and /p/ which are not common in Arabic dialects arise almost exclusively from (predominantly French) loanwords  A study of Northwestern Algerian Arabic (specifically around Oran) showed that laterals /l/ or /ɫ/ or the nasal consonant /n/ would be dissimilated into either /n/ in the case of /l/ or /ɫ/; or /l/ or /ɫ/ in the case of n when closely preceding a corresponding lateral or nasal consonant.
