"Eu quero chamar meu filho."

Translation: I want to call my son.

[Danikalifornia]

Eu quero chamar o meu filho. (I can use o meu filho, right?)

[Paulenrique]

Yes!

[starsfire]

call, as in, on the phone? or yell and hope he comes

[Paulenrique]

The latter option.

For the first one, use "Ligar" instead.

[BTHurley]

I'd (would) like to call or I like to call?I don't see a conditional.

[FernandoSato]

"Eu quero..." = 'I want to...', not "Eu gostaria..." = 'I would like to'... There is no conditional here.
