evolución
/eboluˈθjon/ · B2 · noun · f
development
🦎🐒 e- (out) + volución from volvere (roll): an unrolling out, like a scroll opening
From Latin evolutio, meaning an unrolling, built from e- (out) + volvere (to roll, turn). Think of a scroll unrolling bit by bit: development unfolds gradually. The same volv- root appears in volver (to return) and revolución.
