These are words that modify adjectives and other adverbs. They are usually formed by adding ly to the root word. Some examples would be lovely, totally, worldly and boldly.

Adverbs answer questions

Interrogative adverbs

    These adverbs ask questions: when, where, why and how.
    When shall I see you next?

Degrees of comparison

    There are three levels of comparison: positive - equality or no comparison, comparative - compares two or more persons or things, superlative - compares three or more persons or things.
    Jane is lovely.
    Jane is more lovely than Joan.
    Jane is the loveliest of all the girls in the course.

Position of the adverbs only and not

    These words should be positioned closest to the word they modify because of the difference of meaning when they are not.
    See booklet #4 - 101 Grammatical Tips for examples.

Double Negatives

    The words hardly, merely and scarcely do not require a negative.
    There were hardly any people attending the meeting.
