## Korean
### Etymology

First attested in the Beonyeok sohak (飜譯小學 / 번역소학), 1517, as Middle Korean 고〯맙다〮, attested only in conjugated forms.
The word is almost certainly a contraction of *고〯마〮ᄒᆞᆸ다〮 (*kwǒmáhòptá), the regularly derived —브 (-beu) adjective from the verb 고〯마〮ᄒᆞ다〮 (Yale: kwŏmáhòtá, “to respect; to admire”). In Middle Korean, 고〯맙다〮 (kwǒmàptá) had the meaning of "to be worth respecting; to be worth admiring", as would be expected from regular 브 (-pu-) adjectives. The source verb was displaced by Sino-Korean loans in the Early Modern period, when the derived adjective's semantic shift to "to be thankful" also occurred.

### Pronunciation

* (SK Standard/Seoul) IPA: [ˈko̞(ː)ma̠p̚t͈a̠]
* Phonetic hangul: [고(ː)맙따]
** Though still prescribed in Standard Korean, most speakers in both Koreas no longer distinguish vowel length.

### Adjective

고맙다 • (gomapda) (irregular, infinitive 고마워, sequential 고마우니)
* (to be) thankful
    Synonym: 감사하다 (gamsahada) (more formal)
    This adjective is often translated as a form of “to thank”.
    고맙습니다 ― gomapseumnida ― thank you
    서둘러 주시면 고맙겠소이다.Seodulleo jusimyeon gomapgetsoida.I'd appreciate it if you'd hurry up about it.

#### Conjugation

고맙다 (gomapda) is in the class of irregularly-inflected words whose stems end in ㅂ (b). In such words with two syllables or more, vowel harmony in inflections was once followed in both standardized forms of Korean. With the 1988 한글 맞춤법 (han'geul matchumbeop, “Hangeul Orthography”), the South Korean standard now ignores the vowel harmony, while it is kept in the North.
