to grow dark

Usage Note

Oscurecer can be transitive ('to make dark') or intransitive/reflexive (oscurecerse, 'to become dark'). The impersonal oscurece ('it gets dark') is used for nightfall, parallel to anochecer. An alternate spelling obscurecer exists but oscurecer is now standard across the Spanish-speaking world. The stem vowel undergoes an -zc- insertion in some conjugations: oscurezco.
