What are cardinal numbers?
Cardinal numbers are basically regular ol’ numbers. They simply indicate the number of people, animals, or things.
Eu tenho três irmãosI have three brothers
Ela tem dez pássarosShe has ten birds
Vocês compram vinte laranjasYou buy twenty oranges
They are invariable, except…
The majority of cardinal numbers are invariable, meaning they only have one form. For example, you say três meninos (3 boys) and três meninas (3 girls). There is only one form of três, and most other cardinal numbers.
There are a few important exceptions, however: umone , doistwo , and the centenashundreds starting at 200, do change form depending on the gender of the noun. For example:
- Um copoOne glass → Uma mesaOne table
- Dois carrosTwo cars → Duas casasTwo houses
- Duzentos eurosTwo hundred euros → Duzentas formigasTwo hundred ants
Cem or Cento?
Another variation to note is cem vs. cento, but it’s not related to gender this time.
The word cem100 is used when it stands on its own, when it comes before a noun, and when talking about higher quantities.
cem pássarosone hundred birds
cem mil dólaresone hundred thousand dollars
However, when is followed by a lower number, we use cento.
cento e dezone hundred and ten, 110
cento e vinteone hundred and twenty, 120
Would you consider using the “and” as in “one hundred and twenty “? It is the more literal translation, which stresses the importance of the “and” in Portuguese.
Sure. Thanks!
Getting better
You can just use the same cardinals for anything you count… this is so much easier than Japanese!!
I continue to be delighted with the way you have presented the lessons. It is taking time but definitely improving. Obrigada.
I’ve been searching and searching, but can’t find a simple list of cardinal numbers (ex. 1-100) in this unit or anywhere in the app.🧐
In this Learning Note you can find that list: https://www.practiceportuguese.com/learning-notes/numbers/
So saying ‘without cheese’ sounds exactly the same as saying ‘a hundred cheese’. being vegan must be hard in portugal
In “a hundred cheese”, we’d pluralize ‘cheese’ to ‘queijos’ (keeping it singular in “without cheese”) 🙂 That should help a bit!
How do you differentiate between “a thing” and “one thing”. If we take an example of “a table” and “one table”, aren’t they both “uma mesa”? How do you differentiate these? Thanks for the great app 👍
You don’t, except through context 🙂 It’s probably hardly ever an issue, in practice.
