I've just seen a sentence "Which one is more correct?"

In my native lanuage, there are a few adjectives which don't have comparative and superlative forms. For example "correct, wrong, blind, deaf, dead etc." because there can't be something "more/the most correct/wrong/blind/deaf/dead...". If someone is dead. Someone else can't be more dead. Emotion: big smile The same with the others. It's like black and white. If something is white, something else can't be "more white" Emotion: big smile.

Thank you in advance.

Yes, I suppose some adjectives are absolute. 'More dead' sounds very odd.

Yet we do say eg 'Which one is more correct?', and we seem easily able to find a meaning in it.Emotion: stick out tongue

Sometimes we say 'more correct/wrong' in my native language as well. But it's more of describing suitability than correctness. Because if you say that something is 'more correct' it means that both options are correct, but the 'more correct' option is more suitable for the situation. Therefore more correc't doesn't have to mean 'more grammatical' Emotion: big smile
