| 動 | 
| うご Grade: 3 |

From Old Japanese. Attested in the Kojiki of 712.[1] From Proto-Japonic *unkoku.
Likely derived as a compound of うご (ugo, a 擬態語 (gitaigo, “mimetic word”) imitative of something crawling or creeping; compare the sound shapes of roots wrig- or wig- in English wriggle, wiggle) + く (ku, verb-forming suffix).[1] Compare also the related adverb うごうご (ugougo, “wrigglingly, squirmlingly, creepingly: moving in continuous small increments”).
