hacer
/aˈθeɾ/ · A1 · verb
to do, perform, execute, carry out
🔨 From Latin facere (to make/do): Latin f- became silent h- in Spanish
Latin facere gave English fact, factory and manufacture. Spanish turned the initial f into a silent h, so facere became hacer. Swap the h back to f and the link to factory (a place where things are made) is clear.
