• (Tokyo) おおぜー [òózéé] (Heiban – [0])^[1]

• 大勢順応(おおぜいじゅんのう) (ōzei junnō)

Shift in reading of taisei below. Ultimately from Middle Chinese 大勢 (MC dajH syejH). Uses the kan'yōon of zei for the second character, indicating a shift in pronunciation after borrowing.

From Middle Chinese 大勢 (MC dajH syejH). The kan'on, so likely the reading as borrowed from Chinese.

• IPA^(key): [ta̠ise̞ː]

大(たい)勢(せい) • (taisei)
