Questions & Answers about El mecanismo mueve la pared.
Mueve is the third-person singular present tense of mover.
The subject here is el mecanismo, which is singular, so Spanish uses the he/she/it form:
- yo muevo
- tú mueves
- él/ella mueve
Also, mover is a stem-changing verb. Its o changes to ue in stressed forms:
- muevo
- mueves
- mueve
- movemos
- movéis
- mueven
So mueve is not irregular in a random way; it follows a common Spanish pattern.
