Maasai (Masai) or Maa (English pronunciation: //; autonym: ɔl Maa) is an Eastern Nilotic language spoken in Southern Kenya and Northern Tanzania by the Maasai people, numbering about 800,000. It is closely related to the other Maa varieties: Samburu (or Sampur), the language of the Samburu people of central Kenya, Chamus, spoken south and southeast of Lake Baringo (sometimes regarded as a dialect of Samburu); and Parakuyu of Tanzania. The Maasai, Samburu, il-Chamus and Parakuyu peoples are historically related and all refer to their language as ɔl Maa. Properly speaking, "Maa" refers to the language and the culture and "Maasai" refers to the people "who speak Maa."
The Maasai variety of ɔl Maa as spoken in southern Kenya and Tanzania has 30 contrasting sounds, which can be represented and alphabetized as followsː a, b, ch (a variant of sh), d, e, ɛ, g, h, i, ɨ, j, k, l, m, n, ny, ŋ, o, ɔ, p, r, rr, s, sh (with variant ch), t, u, ʉ, w, wu (or ww), y, yi (or yy), and the glottal stop ' (or ʔ).
Tone is extremely important for conveying correct meaning in the Maasai language.
In the table of consonant phonemes below, phonemes are represented with IPA symbols. When IPA conventions differ from symbols normally used in practical writing, the latter are given in angle brackets.
For some Maasai speakers, the voiced stop consonants are not particularly implosive (e.g. IlKeekonyokie Maa), but for others they are lightly implosive or have a glottalic feature (e.g. Parakuyo Maa). In Arusha Maa, /p/ is typically realized as a voiceless fricative [ɸ], but in some words it can be a voiced trill [ʙ]. At least in native Maa words, [tʃ] and [ʃ] occur in complementary distribution, with the former occurring directly after consonants and the latter elsewhere.

Word order is usually verb–subject–object, though order can vary because tone is the most important indicator of subject versus object. What really determines order in a clause is topicality; order in the most simple clauses can be predicted according to the information structure pattern: [Verb – Most.Topical – Less.Topical]. Thus, if the object is highly topical in the discourse (e.g. a first-person pronoun), and the subject is less topical, then the object will occur right after the verb and before the subject.
The Maasai language has only two fully grammatical prepositions, but can use "relational nouns" along with a most general preposition to designate specific locative ideas. Noun phrases begin with a demonstrative prefix or a gender-number prefix, followed by a quantifying noun or other head noun. Other modifiers follow the head noun, including possessive phrases.
In Maasai, many morphemes are actually tone patterns. For example:
ɛ́yɛ́tá ɛmʊtí Gloss: remove.meat pot.ACC Translation: "She removed meat from the pot."
ɛyɛ́ta ɛmʊ́ti Gloss: remove.meat.MID pot.NOM Translation: "The pot is de-meated."
The Maasai language carries three forms of gendered nouns; feminine, masculine, and place. Native speakers of the language attach a gendered prefix to a noun. The meaning of the noun in context then refers to its gender. Nouns place gender as follows:
"Who has come?" would be asked if the gender of the visitor were known. The noun would be preceded by a gendered prefix. If the gender of the visitor were unknown, "it is who that has come?" would be the correct [English translation] question.
