많다 - Wiktionary, the free dictionary

From Wiktionary, the free dictionary

First attested in the Yongbi eocheon'ga (龍飛御天歌 / 용비어천가), 1447, as Middle Korean 만〯ᄒᆞ다〮 (Yale: mǎn-hòtá), equivalent to 만〯 (Yale: mǎn) + ᄒᆞ다〮 (Yale: hòtá, > modern 하다 (hada)).

The first element is usually, though somewhat speculatively, connected to Sino-Korean 萬 (mǎn, “ten thousand; myriad; (figuratively) countless”).^[1] Displaced native 하다〮 (Yale: hàtá, “to be many”).

• (SK Standard/Seoul) IPA^(key): [ˈma̠(ː)ntʰa̠]
• Phonetic hangul: [만(ː)타]
  • Though still prescribed in Standard Korean, most speakers in both Koreas no longer distinguish vowel length.
