ye- and yo- differ from other verbs in that their infinitives cannot be predicted from the stem. Some verbs retain the initial y-; the remainder drop it and the ku- of the infinitive is replaced by kw-, e.g., yamba, kuyamba; yagala, kwagala; yenga, kuyenga; yera, kwera; yomba, kuyomba; yokya, kwokya. For verbs of the above type the infinitive is listed immediately after the simple form.
