R.

R has two sounds: (1) rough; as in rain, river, &c. e. g., kahore, rorea, roro, roto.

(2) The second is more soft, and is formed by a gentle jar of the tongue against the palate; so gentle indeed is the vibration, that most foreigners pronounce it like d or l, as in raro, ruru, rimu, pouaru, pari, muri, mariri, koiri, korikori, kouru, maru.
