víspera
/ˈbispeɾa/ · B2 · noun · f

🌙 víspera = VIS-pera, like 'vesper' (evening) — the evening before the big day
Víspera comes from Latin vespera, meaning evening. English 'vespers' (evening prayer) shares this root. The evening before a holiday or event became the víspera, as in la víspera de Navidad (Christmas Eve).
