這是語法錯誤,This is not correct grammar. invalidate is a verb, feeling is a noun.
You can, however, say "invalidate a feeling". That is grammatically correct. But it doesn't make much sense.
You could also say "invalid feeling". still, I don't understand what that means. feelings are neither valid nor invalid..... are they? maybe...
這兩個說法語法正確,但是意思不太清楚, invalid跟feeling不太合適。
can you use it in a sentence?
