Yes, we can. It's just easier to omit the pronoun, as the verb is in a different form. :)
is the ę sound in lubię different from other "ę"s in other words?I think it sounds different
Generally, you pronounce it the same way in most words, but in some we don't emphasize it much. Especially endings like here 'Lubię, śpię, myślę' are usually pronounced like normal Polish 'e'.
Am i the only one getting confused with all the diffwrent ways to say like and have?
