Mbalanhu is a Wambo dialect, assigned to Guthrie's R.20, and spoken by approximately 50320 people in Central Northern Namibia. Apart from a limited number of articles by the same author, no linguistic data on the structure of Mbalanhu is available. The sketch commences with a section on phonology. This is followed by a description of noun classes and nominal suffixes in the next section which also contains a treatise of the derivation and structure of several concords (e.g subject­, object­, possessive­), and nominal qualifiers. The third section focuses on verbal conjugation in the dialect, while the final section deals with syntax. The formal grammatical description is a Mbalanhu narrative text accompanied by an interlinear transcription and English translation. This compact sketch incorporates several tables with data, and an abundance of examples. It should form a welcome addition to linguistic material on the R.20 languages/dialects, which, due to a situation of prolonged military conflict in Southern Angola and Northern Namibia, have been inadequately studied to date. 2nd printing.
