Questions & Answers about Onde está o meu computador?
Why is there an "o" before "meu"?
In European Portuguese, you almost always need to put a definite article (like o or a) before a possessive word like meu. Literally, the sentence translates to "Where is the my computer?". Since computador is masculine and singular, we use o.
Would a female speaker say "a minha computador"?
Why do we use "está" for "is" here instead of "é"?
Can I leave out the "o" and just say "Onde está meu computador"?
In Portugal, you really shouldn't. While dropping the article before a possessive is very common in Brazilian Portuguese, in European Portuguese the article is mandatory in everyday speech. Dropping it here would sound unnatural to a Portuguese person.
