# -다가
## Korean
### Alternative forms

* 다 (-da) — short form of both

### Etymology 1

First attested in the Worin seokbo (月印釋譜 / 월인석보), 1459, as Middle Korean 다가〮 (Yale: -tàká), from 다ᄀᆞ다 (Yale: tako-ta, “to hold, to have”) + 아〮 (Yale: -á, verbal infinitive suffix). Equivalent to modern 다그 (dageu-) +‎ 아 (-a).

#### Particle

다가 • (-daga)
* An emphatic particle.
    여기다가 두면 되겠소? ― Yeogi-daga dumyeon doegetso? ― Shall it be all right if I put it here?
    톱으로다가 나무를 이렇게 자르시오. ― Tob-euro-daga namu-reul ireoke jareusio. ― Cut the wood with the saw like this.

##### Usage notes

* The particle is attached to 에 (-e, “at”), 에게 (-ege, “to”), 한테 (-hante, “to”), and 으로 (-euro, “with, by”), and with certain adverbs or nouns referring to place, direction, or means. Historically, it could also combine with 을 (-eul, accusative case marker), but this is now fully obsolete.

### Etymology 2

First attested in the Cheoyong-ga (處容歌 / 처용가), 1281, as Late Old Korean 如可 (Yale: *-taka). The Cheoyong-ga is claimed to be from the ninth century but is almost certainly of much later provenance, possibly as late as the thirteenth century. Not attested in earlier Old Korean sources.
In the hangul script, first attested in the Seokbo sangjeol (釋譜詳節 / 석보상절), 1447, as Middle Korean 다가〮 (Yale: -tàká).
Further etymology unclear. In 13th century gugyeol texts, this suffix appears as 入舍可 (*-tosyaka) when fused with the honorific suffix 으시 (-usi-). This suggests that it is a compound of 더〮 (Yale: -té-, imperfect past suffix) + 오〮 (Yale: -wó-, unclear suffix, perhaps the modulator) + 가〮 (Yale: -ká, unclear suffix).
However this is incompatible with the tonal pattern, as the syllable 다 has low pitch rather than the high pitch expected from this etymology. Perhaps the pitch was affected by that of the particle, although Kim Seong-gyu rejects this possibility.
