Saying "Other" and "Another"
In English, we distinguish between "another" (singular) and "other" (plural or uncountable). In Portuguese, you simply use a single word for both: outro.
Like other determiners, outro must agree in gender and number with the noun it describes, giving you four forms: outro, outra, outros, outras. It can be placed directly before a noun, or it can stand alone as a pronoun to avoid repeating a word.
Contracting with Prepositions
Just like the definite articles (o, a) and demonstratives (este, aquele), outro merges with the common prepositions em (in/on/at) and de (of/from).
| Preposition | + outro | + outra | + outros | + outras |
|---|
| em (in/at) | noutro | noutra | noutros | noutras |
| de (of/from) | doutro | doutra | doutros | doutras |
When browsing vehicles at a dealership, you will frequently use the em contractions to talk about looking at or in another location or model.
Likewise, when talking about the price, warranty, or features of a different car, you will use the de contractions.
Notice how in many of these sentences, noutro or doutro can stand completely on its own, acting as a pronoun meaning "in another one" or "of another one" based on the context of the conversation.
