## Japanese
### Etymology 1

Kanji in this term :
| 所 | 為 |
| しょ Grade: 3 | い Grade: S |
| goon | on'yomi |
* Alternative spellings
* 所爲 (kyūjitai) 所意
From Middle Chinese 所為 (MC srjoX hjwe|hjweH). The goon, so likely the initial borrowing.

#### Pronunciation

* (Tokyo) しょい [shóꜜì] (Atamadaka –)
* IPA: [ɕo̞i]

#### Noun

所(しょ)為(い) • (shoi)
* one's deed
* cause, reason

### Etymology 2

Kanji in this term :
| 所 | 為 |
| しょ > せ Grade: 3 | い Grade: S |
| irregular | on'yomi |
* Alternative spellings
* 所爲 (kyūjitai) 故 (literary)
*/sjowi/ → */sjoi/ → /ɕoi/ → /ɕei/ → /sei/ → /seː/
Probably a shift from shoi above.

#### Pronunciation

* (Tokyo) せー [séꜜè] (Atamadaka –)
* IPA: [se̞ː]

| 所 | 為 |
| そ Grade: 3 | い Grade: S |
| kan'on | on'yomi |
