Historical Evolution
Swahili arose on the East African coast from Bantu substrates and Arabic superstrata through Indian Ocean commerce. Zanzibar and Bagamoyo varieties fed colonial standardization; Tanzania adopted it as the national language after independence. Latin script (Swahili orthography) replaced Arabic script in most secular contexts.
Phonology
Swahili has five vowels and simple open syllables; stress is penultimate. Arabic loans may introduce consonants like /θ/, /ð/, /x/ in educated speech, but core phonology remains Bantu. Nasal harmony affects prefix allomorphy (m-/n-/ng-).
Syntax
Swahili is SVO with rich noun-class agreement: prefixes on nouns, adjectives, verbs, and demonstratives cross-reference class and number. Verbal derivational extensions (-isha causative, -anz- reciprocal) agglutinate. Tense-aspect markers are prefixal on the verb stem.
