Understanding “Cujo” and “Cuja” in Portuguese
“Cujo” and “cuja” are relative pronouns used to indicate possession, similar to the English “whose.” They connect two clauses by showing a relationship of ownership between a noun in the main clause and another noun in the subordinate clause.
Grammatical Rules for Using “Cujo” and “Cuja”
1. Agreement in Gender and Number
The pronoun “cujo” must agree in gender and number with the noun that comes immediately after it, not the noun it refers to. This is a key rule that differentiates its use from English:
- Cujo: Masculine singular
- Cujos: Masculine plural
- Cuja: Feminine singular
- Cujas: Feminine plural
Example:
- O escritor cujo livro eu li mora aqui. (The writer whose book I read lives here.)
- A mulher cuja filha estuda comigo é minha vizinha. (The woman whose daughter studies with me is my neighbor.)
2. Placement of “Cujo” and “Cuja”
“Cujo” and “cuja” always appear between two nouns, never at the beginning or end of a sentence. The noun following “cujo/cuja” is always the possessed item.
Example:
- Conheci o artista cuja obra admiro. (I met the artist whose work I admire.)
3. No Article After “Cujo” or “Cuja”
Unlike some English constructions, “cujo” and “cuja” are never followed by a definite or indefinite article (o, a, os, as, um, uma, etc.). This is a frequent mistake among learners.
Incorrect: O aluno cujo o professor é famoso…
Correct: O aluno cujo professor é famoso…
4. Expressing Possession Clearly
Only use “cujo” or “cuja” when you need to express possession connecting two nouns. If the sentence does not require this structure, use other relative pronouns like “que” or “quem.”
Example:
- O médico cujo consultório fica no centro. (The doctor whose office is downtown.)
Common Mistakes and How to Avoid Them
- Confusing the agreement: Always check the gender and number of the noun following “cujo/cuja.”
- Adding articles after “cujo/cuja”: Remember, no article should come after these pronouns.
- Incorrect placement: Ensure “cujo/cuja” is placed between the two nouns it links.
