[Grammar] Superlatives

[hugomlazaro]

would like a better explanation on the superlative, when should I use "most" and when not I use.

Adjectives of a single syllable usually form the comparative and superlative by means of suffixes; for example: quick, quicker, quickest.

Adjectives of more than one syllable usually form the comparative and superlative by means of more and most; for example, convenient, more convenient, most convenient.

There are however many exceptions to this rule, and you have to learn them one by one.
