I was wondering if an adjective 'terrible' is either gradable or non-gradable. Is it correct to say:
It's really terrible.
Thank you in advance for an answer.
The word terrible is generally considered to be non-gradable. The phrase "very terrible" sounds awkward and "slightly terrible" only makes sense as an ironic or humorously self-contradictory phrase.
However, the sentence "It's really terrible" does sound perfectly natural to me, but that's because I don't interpret the word really as an intensifier in this situation, but as a synonym of actually or genuinely. So the sentence is correct, but has the meaning, "Actually, it's terrible."
