§ 38. Voice and Tense. The only inflexion of the original form of the verb is in the formation of the Passive Voice, and consists in the addition of a Passive termination to the Active form.
Differences of Tense are denoted by certain auxiliary particles, the same form in each case serving for all persons and numbers. Some of these particles vary, or are differently used in negative sentences, and some of the tenses have their own peculiar negative adverb, and admit of no other, as will be seen in the following example.
ACTIVE VOICE.
1. Present.
E pupuri ana ahau, I hold, or am holding.
Kahore ahau e pupuri ana, I am not holding.
2. Perfect.
Kua pupuri ahau, I have held.
