## Middle Korean
### Etymology

This is one of four related Middle Korean interrogatives all beginning with /mɨsɨ-/: 므스 (musu), 므슥 (musuk), 므슴 (musum), and 므슷 (musus). The precise etymological relationship between the four remains unclear.

### Pronunciation

* IPA: /mɨsɨm/

### Pronoun

므슴〮 (mùsúm)
* (interrogative) what
** 1475, Queen Insu, 內訓 / 내훈 [Instructions for Women]‎, page 1:43a:孝(효)道(도) 아니 ᄒᆞ면 너를 어더 므슴ᄒᆞ료HYWO.TWO ani homyen ne-lul ete musum holywoIf you do not practice filial piety, what would be the point of having you?
** 1496, 六祖法寶壇經諺解 / 육조법보단경언해 [Korean Translation of the Platform Sutra of the Sixth Patriarch], page 中:7a:定(뎌ᇰ)慧(혜)ᄂᆞᆫ 므슴과 ᄀᆞᆮᄒᆞ뇨TYENG.HYEY-non musum-kwa kot-honywoWhat do certitude and wisdom resemble?

#### Usage notes

* 므스 (musu) is used before the interrogative particle 고 (-kwo).
* 므슴 (musum) is used before other consonant-initial particles, and before the verb ᄒᆞ다〮 (Yale: hò-tá) "to do".
* 므슥 (musuk) is used before vowel-initial particles.
* In the Early Modern period, the pronouns are ultimately supplanted by the new pronoun 므엇 (mwues), whence modern 무엇 (mueot), 뭐 (mwo).

### Determiner

므슴〮 (mùsúm)
* (interrogative, often rhetorical) what
    Synonym: 어느 (enu)

#### Usage notes

* 므스 (musu) is used only for the semantically weak nouns 것 (kes, “thing”) and 일 (il, “work, event”).
* 므슴 (musum) is used generally, but typically in rhetorical questions.
* 므슷 (musus) is used primarily for 일 (il, “event”) but is rarely attested elsewhere.
* 므슷 fails to survive into Early Modern Korean, while 므스 vanishes near the end of the eighteenth century. The default Early Modern interrogative determiner is 므슴, which loses its rhetorical sense and becomes a general interrogative determiner.
* 므슨 (meuseun), probably a hypercorrection of 므슴 motivated by the adnominal ending 은 (eun), is first attested in 1637 and becomes more widespread than 므슴 around 1850, producing Modern Standard Korean 무슨 (museun).

#### Descendants

* ⇒ Early Modern Korean: 므슨 (musun, “what”)
** Korean: 무슨 (museun, “what”)

### Adverb
