Yukpa language

Yukpa is a Cariban language, spoken by 3,000 people in Zulia State in Venezuela and 3,000 across the border in Colombia. It is also known as Carib Motilón, Macoíta, Northern Motilón, and Manso.
Río Casacará and Río Maracas are the main dialects, and different enough to possibly be considered separate languages. Also Caño Padilla–La Laguna. The Venezuelan dialects, Yrapa and Río Negro, are closer to Río Maracas than to Río Casacará.
Similarity to Japrería, the other Yupka language, is slight.

Phonology

Consonants

Sounds /p, m/ can become velarized as when before vowels /e, a/.
/j/ can have an allophone of in free variation, and when before consonants.
A retroflex may also occur simultaneously in the place of /tʂ/ or /ʂ/ in the Sokorpa dialect.
In the La Paz and Menkwe dialects, retroflex consonants do not occur, so /ʂ/ is heard as in both dialects, and /tʂ/ is heard as either in the La Paz dialect, and in the Menkwe dialect.
Nasal sounds /m, n/ become voiceless when preceding voiceless stops.

Vowels

/e/ ranges between sounds across dialects.
