Japanese
Etymology 1
| Alternative spellings |

| 煙 烟 (uncommon) |
/kemuri/ → /kemu/
Clipping of 煙 (kemuri, “smoke”).[1][2]
Attested since at least 1275.[1]
Etymology 2
⟨ke1mu⟩ → */kʲemu/ → /kemu/
From Old Japanese けむ. Attested in the Kojiki of 712[1] and the Man'yōshū of 759 and earlier.[1][5]
Various theories exist regarding the ultimate derivation of this auxiliary verb suffix.[1][5][2]
- Compound of け (ke, a hypothetical 未然形 (mizenkei, “irrealis or imperfective form”) of past-recollective auxiliary き (ki), usually found instead as せ (se)) + む (mu, suppositional auxiliary suffix).[1][2]
- The ke conjugation for past-recollective き (ki) is only hypothetically considered to be the irrealis form. This ke is not found outside of a small handful of suffixes such as this けむ (kemu), its derivative けまく (kemaku), and separate けく (keku), and it remains largely unexplained. That said, the initial /s-/ ↔ /k-/ alternation exhibited in the better-documented conjugated forms is also largely unexplained.
- Compound of 来 (ki, “coming”, the 連用形 (ren'yōkei, “continuative or stem form”) of verb 来る (kuru, “to come”)) + 経 (he, “passing through, as of a process or time or place”, the 連用形 (ren'yōkei, “continuative or stem form”) of verb 経る (heru, “to pass through”)) + む (mu, suppositional auxiliary suffix).[1]
- */ki pe mu/ → */kifemu/? → */kiemu/ → /kemu/
- Due to the presence of initial /p-/ in the medial Old Japanese 経 (pe, continuative stem, terminal form was pu), the phonological shifts required for this derivation ultimately make this theory seem quite unlikely: linguists generally reconstruct initial /p-/ for Old Japanese and hold that this did not undergo lenition until the late Nara period (710–794) or early Heian period (794–1185), while ⟨ke1mu⟩ → /kʲemu/ is already attested in the Kojiki of 712.
- Compound of き (ki, past-recollective auxiliary suffix) + あむ (amu, hypothetical earlier form of suppositional auxiliary suffix む (mu)).[1][5]
- */ki amu/ → */kiamu/ → /kʲemu/ → /kemu/
- This hypothetical reconstructed amu form for the suppositional suffix is favored by linguists such as Bjarke Frellesvig and Alexander Vovin.
