Is there any difference in meaning among the 3 following sentences?
What I meant was whether that is correct or not.
What I meant was whether that was correct or not.
What I meant was whether that would be correct or not.
If so, an explanation will be great.
Also is the 1st sentence semantically/grammatically correct? (could using "is" & "was" in the same sentence make the meaning of the sentence ambigous here?)
