The Mandinka language (; Ajami: ) or Mandingo, is a Mande language spoken by the Mandinka people of Guinea, northern Guinea-Bissau, the Casamance region of Senegal, and in The Gambia where it is one of the principal languages. Mandinka belongs to the Manding branch of Mande and is thus similar to Bambara and Maninka/Malinké but with only 5 instead of 7 vowels. In a majority of areas, it is a tonal language with two tones: low and high, although the particular variety spoken in the Gambia and Senegal borders on a pitch accent due to its proximity with non-tonal neighboring languages like Wolof. Phonology Mandinka is here represented by the variety spoken in Casamance. There is little dialectical diversity. Tone Mandinka has two tones, high and low. Unmodified nouns are either high tone on all syllables or low tone on all syllables. The definite suffix -o takes a low tone on high-tone nouns and a falling tone on low-tone nouns. It also assimilates any preceding short vowel, resulting in a long /oo/ with either low or falling tone. It shortens a preceding long high vowel (ii > io, uu > uo; ee optionally > either eo or ee) or assimilates itself (aa remains aa) leaving only its tone: /búŋ/ 'a room' > /búŋò/ 'the room' /tèŋ/ 'a palm tree' > /tèŋô/ 'the palm tree' /kídí/ 'a gun' > /kídòò/ 'the gun' /kòrdàà/ 'a house' > /kòrdáà/ 'the house' In Senegal and Gambia, Mandinka is approaching a system of pitch accent under the influence of local non-tonal languages such as Wolof, Serer, and Jola. The tonal system remains more robust in the Eastern and Southern Mandinka dialects (Tilibo) spoken in the Guinea-Bissau, Guinea and Eastern Senegal. These conservative dialects merge into other conservative Manding languages like Maninka, the once official language of the Mali Empire, Bambara, and Susu. All of these preserve the typical West African terraced downstep in tonality that is only lightly alluded to in the Western Mandinka dialects spoken in much of Gambia and Senegal. Vowels Vowel qualities are . All may be long or short. There are no nasal vowels; instead, there is a coda consonant /ŋ/. Long vowels are written double: aa, ee, ii, oo, uu. Consonants The following table gives the consonants in the Latin orthography, and their IPA equivalent when they differ. Syllabic nasals occur in e.g. nnààm 'yes!' (response), ŋte "I, me".
