Premodifiers are usually adjectives, which come before a noun and modify its meaning. When placed before an adjective, a premodifier describes the adjective and alters its meaning.

There are three degrees of adjectives: positive, comparative and superlative. Positive adjectives are words or phrases that express something about the noun itself. Comparative adjectives express something about a noun as compared to another noun. Superlative adjectives compare the noun to more than two nouns.

This is an example of an adjective used in the positive degree: “The poor man begs.” (The adjective is “poor.”)
This is an example of the comparative degree: “The poorer man begs more.” (The comparative adjective is “poorer.”)
And, finally, the superlative degree is shown here: “The poorest man begs most.” (The superlative is “poorest.”)
When preceding words that don’t admit of -er or -est endings, ‘more,’ ‘less,’ ‘most’ and ‘least’ count as part of the adjective phrase.

Using premodifiers with degrees of adjectives either intensifies or dulls the adjective. Consider the example, “I’m feeling a little better.” The phrase “a little” modifies the meaning of “better,” and is, therefore, a premodifying phrase. Following is a list of other premodifiers used with the comparative degree:

slightly
a bit
much
rather
somewhat
a lot more

The premodifier “very” can be used with the superlative degree of adjectives to add emphasis. It must be preceded by a determiner, like ‘my,’ ‘a,’ and ‘the.’
For example, “She’s my very best friend.” Or, “You’re the very worst driver!”
