Portuguese Phrase
Boa noite.
Meaning
This phrase serves as both a greeting and a farewell during the evening and nighttime hours. Unlike English, which distinguishes between 'good evening' (greeting) and 'good night' (farewell), Portuguese uses this single expression for both contexts.
When to use
Use this phrase from sunset until sunrise. It is suitable for arriving at a restaurant, greeting friends at a party, or saying goodbye before going to bed.
