Questions & Answers about Na sexta-feira, precisamos terminar o projeto antes do prazo.

Why is it na sexta-feira?

Na is a contraction of em + a.

• em = in / on / at
• a = the (feminine singular article)

So:

• na sexta-feira = literally on the Friday
• In natural English, we usually just say on Friday

In Brazilian Portuguese, days of the week often appear with the article:

• na segunda-feira
• na terça-feira
• na sexta-feira

You may also hear shorter versions in speech, depending on the sentence, but na sexta-feira is a very standard and natural way to say on Friday.

Why is sexta-feira written with a hyphen?

The weekday names in Portuguese are normally written with a hyphen:

• segunda-feira
• terça-feira
• quarta-feira
• quinta-feira
• sexta-feira

This is just the standard spelling.

Historically, feira is part of the traditional naming system for weekdays in Portuguese. So sexta-feira is not two separate words in modern spelling; it is one hyphenated expression.

Why does sexta-feira literally seem to mean sixth fair/market?
