Okay, so I put "To dziecko po angielku" which I realise now is wrong because I forgot 'mówi', but it corrects me to "To dziecko zna angielski".
Why? What would make this different to "To dziecko mówi po angielku"?
Can you tell me why it's mówi not mówię. What word am. I supposed to be looking at to tell me what form of to speak should I use. I thought the child would indicate the form to use (and maybe just got it wrong anyway)
