Is there a term to describe the case where using "-er" and "-est" is incorrect to form a comparative because it is formed by using "more" or "most"?
For example:
more difficult instead of difficulter
most difficult instead of difficultest

Multisyllabic adjectives use "more" to form the comparative and "most" to form the superlative. Irregular comparatives (good, better, best; bad, worse, worst) follow neither the rule for one syllable adjectives nor the rule for multisyllabic adjectives. Two-syllable adjectives admit to the multisyllabic "more" and "most" but many will also take "er" and "est," and some prefer it (disyllables in y, for example, and the trisyllabic negative forms of those disyllables: holy: holy, holier, holiest; unholy, unholier and unholiest.
