사대

Korean

Sino-Korean word from 事大, from 事 (“serve”) + 大 (“great [state]”), often attributed to a saying in Mencius (translation by James Legge):

惟智者為能以小事大。／惟智者为能以小事大。

And it requires a wise [ruler] to be able with a small State to serve a great.

(SK Standard/Seoul) IPA^(key): [ˈsʰa̠(ː)dɛ] ~ [ˈsʰa̠(ː)de̞]
Phonetic hangul: [사(ː)대/사(ː)데]
- Though still prescribed in Standard Korean, most speakers in both Koreas no longer distinguish vowel length.
