Rāhina
1. (noun) Monday.
I ngā rā o mua, ko te Mane te rā whakanui i te marama. Nā runga i tēnei āhua, ka whakaarahia ake tētahi o ngā kupu tawhito mō te marama, arā ko māhina. Ka tāpirihia tēnei ki te kupu 'rā', ka whakataka mai ai ko te mā o māhina, kia poto ake ai, kia noho kē mai ko te Rāhina hei ingoa hou mō te Mane (HM 3/1994:7). / In former times Monday was the day celebrating the moon. Because of this aspect, one of the ancient words for the moon has been revived, that is māhina. This word has been appended to the word 'rā', then dropping the mā of māhina so that it's shorter, thus leaving Rāhina as a new name for Monday.
