2. manner; mode; way something appears or behaves
A more technical sense meaning the manner or mode in which something occurs. Used in grammar (様態(ようたい)の助動詞(じょどうし), 'modal auxiliary of appearance', e.g., そうだ meaning 'looks like') and in academic or scientific descriptions of behavior or form.

「そうだ」 is an auxiliary verb that expresses appearance.

Written with 様(よう) ('appearance; state') + 態(たい) ('form; attitude'). Sounds formal and often appears in medical reports, news broadcasts, and academic writing.

USAGE:

  • The most frequent everyday context is news and medical reports on an injured or ill person's condition, where 様態(ようたい) and 容態(ようだい) are near-interchangeable.
  • In grammar instruction, 様態(ようたい) refers to expressions of appearance or likelihood, especially そうだ (e.g., 雨(あめ)が降(ふ)りそうだ 'it looks like it'll rain').
  • Not used in casual conversation about feelings or moods — use 調子(ちょうし) or 具合(ぐあい) instead.
