"A casa está paga."

[microgriff]

I thought 'paga' is present tense 'pays'.. why not the past form here ? is this wrong ?

[Paulenrique]

yes, it is wrong. Paga is the third singular conjugation for the present tense, but also a PARTICIPLE verb, which takes masculine/feminine and singular/plural forms: paga, pagas, pago, pagos. But paga doesn't express past for the 3rd person. Then we say "ela pagou"

So is the correct translation for "The house is paid" is "A casa está pago"?

[Paulenrique]

No. Participles have number and gender in Portuguese. Casa is feminine, so we say "a casa está paga"

ah ok, so Duolingo's answer is correct. I got confused and thought you were saying it was wrong. Cheers!
