superlative and "elative": What is "Elativ" in English?

I always forget that "elative" is no grammar term in English.

In Latin grammars (at least in German ones) "Elativ" is a superlative form that is not translated as superlative but with "very/highly", expressing a high degree but not the absolutely highest degree.

What is the English term for an expression such as: - a most interesting novel

Solution 1:

I have typically seen "most" in your example labeled as an intensifier in English grammar. It's functioning as a grammatical expletive rather than as a true superlative.

Alex B. - do you have a reference for that being called an elative in English? I was not able to find one.
