§ 59. Preposition i. Adjectives and participles are followed by the preposition i (not e, which belongs only to passive verbs), to denote the agency or instrumentality by which the effect has been or is to be produced.
Examples.
Kua ora ahau i to rongoa, I have become well by means of your medicine.
Ka pau tana kai i te kuri, his food is consumed by the dog.
§ 60. Explanatory Verb. Sometimes a verb in the infinitive mood is added to a participle by way of explanation, and in that case the preposition will be different according as the agent is placed after the participle, or after the verb. If after the participle, it will be i: if after the verb, it will be e.
Example.
Ka pau to paraoa i te kuri te kai, or, Ka pau te paraoa te kai e te kuri, the bread is eaten up by the dog (is consumed by eating).
