Questions & Answers about Eu guardei o cartão de cidadão na carteira.

Can I drop the subject pronoun Eu here?

Yes. Portuguese is a pro‑drop language. The most natural version is simply: Guardei o Cartão de Cidadão na carteira. You keep Eu only for emphasis or contrast.

Why is it cartão de cidadão and not cartão do cidadão?

Because de cidadão is a classifier (“citizen card,” the type of card), not “the card of the citizen.”

• cartão de cidadão = the ID document’s name/type.
• cartão do cidadão = the card belonging to a particular citizen (e.g., “the citizen’s card”).

Do I need the definite article o before cartão de cidadão?

Yes, when you mean a specific card. Portuguese uses definite articles more than English: (o) cartão, (a) carteira.

• Guardei o cartão... = I put my/the specific card away.
• Without the article you’d be speaking more generically about the document type.

Should I capitalize Cartão de Cidadão?

When referring to Portugal’s official ID, capitalizing is common and recommended: Cartão de Cidadão. In casual writing you might see lowercase, but the official naming uses capitals.

What does na mean? Why not em a?

Na is the contraction of em + a = “in/on the” (feminine). So na carteira = “in the wallet.”

Does carteira mean wallet or purse in Portugal?

In Portugal:

• carteira = wallet (for cards/cash).
• porta‑moedas = coin purse.
• mala = handbag/purse (what many women carry).
  Note: In Brazil, carteira can also mean “driver’s license” (e.g., “carteira de motorista”), but in Portugal that’s carta de condução.

Do I need to say o meu cartão or na minha carteira?

Not necessarily. Possessives are often omitted when it’s obvious from context.

• Natural: Guardei o Cartão de Cidadão na carteira.
• If you need to be explicit or contrastive: Guardei o meu Cartão de Cidadão na minha carteira.
  Remember Portuguese usually keeps the article with possessives: o meu, a minha.

What nuance does guardar have compared with pôr, meter, or arrumar?

• guardar = to put away/keep/store (often with a sense of safekeeping).
• pôr = to put/place (neutral).
• meter = to put (very common in European Portuguese, informal-ish).
• arrumar = to tidy/put away in its proper place.
  All are possible, but guardar suits “I put it away for safekeeping.”

Why is it guardei (preterite) and not tenho guardado or guardo?

• guardei (pretérito perfeito) = one completed action in the past: “I put it away.”
• tenho guardado (present perfect) = repeated/ongoing up‑to‑now: “I have been keeping/putting it away (habitually).”
• guardo (present) = habitual or current general fact: “I keep it (in the wallet).”

How do I replace o cartão de cidadão with a pronoun?

Use the direct object pronoun o and attach it to the verb (European Portuguese prefers enclisis in affirmative main clauses):

• Affirmative: Guardei-o na carteira.
• Negative or with attractors (e.g., não, já, ainda, nunca): Não o guardei. / Já o guardei.
  Note the hyphen with enclisis. No spelling change is needed with guardei; changes like -lo/-la happen when the verb ends in -r, -s, -z (e.g., guardar → guardá-lo).

What are the genders here, and how do the articles agree?

• cartão is masculine: o cartão.
• carteira is feminine: a carteira; with em + a you get na carteira.
  Everything agrees in gender and number with the noun it modifies.

How do I make this plural?

• Nouns: o cartão → os cartões; o cidadão → os cidadãos; a carteira → as carteiras.
• For the fixed term, the usual plural is to pluralize only the head noun: os cartões de cidadão (official name/classifier sense).
  If you truly mean “the citizens’ cards” (cards belonging to citizens), you can say os cartões dos cidadãos.

Can I say dentro da carteira instead of na carteira?

Yes. Dentro da carteira emphasizes “inside,” while na carteira is the neutral “in the wallet.” Both are natural here.
