różnica między 'normalny' i 'zwykły'?
normalny - normal
zwykły - usual
So in this sentence, does one of them mean that he does not look like most other people and the other that he does not look the way he usually does? And if so, which is which?
I also heard "jest nie normalny", instead of "nie jest normalny", is this also used sometimes?
If you negate an adjective, it's written together: nienormalny. But the meaning changes, sometimes only a bit, and sometimes very much.
"nie jest normalny" is pretty neutral.
"jest nienormalny" is like "is abnormal", "weird", "bizarre" etc.
