Ordinal Numbers

3 min read

Ordinal numbers tell us the order people, animals, or things take in a specific series:
A mulher foi a primeira a chegarThe woman was the first to arrive.
They are variable, meaning they must match the subject in gender and number. For example:
O homem foi o primeiro a chegarThe man was the first to arrive
Eles foram os primeiros a chegarThey (masc.) were the first to arrive
Elas foram as primeiras a chegarThey (fem.) were the first to arrive

Chart of Ordinal Numbers in Portuguese

Here are some of the most commonly used ordinal numbers. (You can find more here: Introduction to Numbers in Portuguese.) The patterns for masculine/feminine and singular/plural forms stays the same throughout (o/a/os/as endings), so we only included full examples for the first few. Use this as an opportunity to practice by speaking aloud the missing ordinal numbers.
