How do you say, "He never played baseball." ?
It is the same.
Please what's the function of "не" in this sentence? Can't ніколи stand alone? For some reason I keep reading this as:
He has never not played baseball.
Ukrainian is a double negative language.
I was answered on other thread that you always use не with ніколи when you want to say a negative sentence. The double negation might sounds weird for my spanish mental mode but it's a different language, nobody say it was easy :)
'He never has played baseball.' Ought to be accepted
