rā
1. (particle) over there, there, yonder - used after nouns, location words, pronouns and personal names to indicate position or connection not near or connected with the speaker or listener or the principal characters in a narrative. It may indicate a spacial distance, or a distance in past or future time as discussed below. Like the other two locative particles, nā and nei, it follows manner particles (i.e. kau, kē, noa, rawa and tonu) and directional particles (i.e. mai, atu, iho and ake) in the phrase, if they are present.
