Learn Portuguese (Portugal): Que camisola tão gira!

To exclaim 'What a [adjective] [noun]!' in Portuguese, the structure is usually Que plus the noun, then tão, and finally the adjective. Literally, this translates to 'What sweater so cute!'.

Is camisola a false friend? It looks like the English word camisole.

Yes, it is a false friend! In European Portuguese, a camisola is a sweater, a pullover, or a sports jersey, not a delicate undergarment.

I thought tão meant so. Why does the English translation say 'What a cute sweater'?

You are right that tão means so. The English translation uses 'a' because that is how we naturally exclaim things in English. However, the Portuguese phrasing literally says 'What sweater so cute!'. Notice that the Portuguese sentence does not use the word for a (uma) at all.

What kind of word is gira?

Gira is the feminine form of giro, which is a very common everyday adjective in Portugal. It means cute, nice, pretty, or cool. It takes the feminine form here to agree with the feminine noun camisola.
