Superlative

A superlative, in grammar, is an adjective describing a noun that is the best example of a given quality. In other words, a superlative describes a noun that has more of some quality than any other. 

Some examples:
the coldest day (i.e. the best example of a cold day, or the day that is colder than all the others)
the craziest man
the fluffiest cloud

In English, most superlatives can be formed by adding -EST to an existing adjective, like the examples above. (For adjectives that end in "-y", like "crazy", one often changes the "y" to an "i" before one adds the -EST on the end.)

Some adjectives have irregular superlative forms, which do not follow the rules, such as far ("farthest") and bad ("worst"). 

Other adjectives have no superlative form at all, and the superlative is made simply by adding the adverb "most" before the adjective. For instance, you do not say "funnest," or "interestingest". Instead, you say "most fun," and "most interesting." 
This way of making the superlative is used for almost all adjectives ending in "ing" (like "interesting", "fascinating", "disgusting" or "appealing".)
