de + Noun
Possession with De
In Portuguese, possession is expressed by placing the possessed object first, followed by the preposition de, and then the owner. Unlike English, there is no 's' (apostrophe-s).
How It Works
The preposition de is the primary way to indicate possession, origin, or relationship in Portuguese.
1. Word Order:
The order is always 'The [Thing] of [Person]'. You cannot say 'Maria's carro'. It must be 'O carro de Maria'.
2. Material and Composition:
Beyond possession, de is used to describe what something is made of. For example: 'uma mesa de madeira' (a wooden table) or 'um copo de vidro' (a glass cup).
3. Mandatory Contractions:
When de is followed by a definite article or a demonstrative, they must merge. This is not optional:
- de + o = do / de + a = da (with definite articles)
- de + este = deste / de + aquela = daquela (with demonstratives)
4. Optional Contractions:
Contractions with indefinite articles, like de + um = dum or de + uma = duma, are common in spoken Portuguese but are often avoided in formal writing.
5. Pronoun Fusions and Agreement:
To say 'his' or 'hers' clearly, Portuguese often uses dele (de + ele) or dela (de + ela). These forms are preferred in speech to avoid confusion with seu/sua, which can mean 'your', 'his', or 'her'.
Crucial Rule: Unlike other possessives, dele/dela agree with the owner, not the object. For example: 'A casa dele' (His house - male owner) and 'O carro dela' (Her car - female owner).
6. Names and Articles:
In Portugal and many parts of Brazil, it is standard to use definite articles before names. In these regions, 'John's house' becomes 'A casa do João' (The house of the John). In other regions or formal writing, the article may be omitted: 'A casa de João'.

Uses the contraction 'do' (de + o) because names often take a masculine article.

Word by Word: The key of the house.
Uses 'da' (de + a) because 'casa' is a feminine noun.
- Onde está o carro dele?
Where is his car?
Word by Word: Where is the car of him?
'Dele' is the contraction of 'de + ele' (of him).
- Os brinquedos das crianças.
The children's toys.

Uses 'das' (de + as) for a feminine plural possessor.
- Este é o escritório do diretor.

Shows a professional relationship/ownership using 'do'.
Common Mistakes
Using an English-style apostrophe-s.
Maria's carro.O carro da Maria.Portuguese never uses apostrophes to show possession. You must use the 'de' construction.
Failing to contract 'de' with the article.
O livro de o professor.O livro do professor.Contractions like 'do' and 'da' are mandatory in Portuguese grammar.
Reversing the word order.
O de Maria carro.O carro da Maria.The possessed object must always come before the possessor.
