The Preterite is marked by the prefixes "do-, ɡo-," and "bi-", the Perfect by "to-, ko-, ʃi-", the Imperfect by"dimá, ɡimá, mi", the Future by "ɡo-, ɡi-," and "da-", and the Pluperfect by "tamą-, kimą-, kamą-." All tenses use the same suffixes as the Present tense for dual and plural numbers and clusivity. The difference between Preterite and Imperfect is similar to the distinction between the Spanish Preterite "habló" 'he spoke (punctual)' and the Spanish Imperfect "hablaba" 'he spoke/he used to speak/he was speaking (non-punctual)'.
