古い和歌に「ももちどり」という表現がある。
In old waka poetry, there is the expression ももちどり (a hundred birds).
noun, used as a prefix
many; a great many
Poetic prefix meaning 'many' or 'countless'. Found in classical compounds like ももちどり (many birds) or ももよ (many nights). Not productive in modern Japanese.
「ももよ」は、多くの夜、長い年月を表す古語です。
ももよ is an archaic word meaning many nights or a long span of time.
The reading もも is an ancient native Japanese word for 'hundred', predating the Sino-Japanese ひゃく. Its origin is uncertain, but it may be related to reduplication or an old counting system.
