florecer
/floɾeˈθeɾ/ · B2 · verb
to flower
🌸 flor- (flower) + -ecer (to become) = to become flowers, to bloom
Spanish flor means flower, and the suffix -ecer marks becoming or starting a state, as in amanecer or crecer. So florecer is literally to become flowery: to bloom, and by extension to flourish or prosper.
