Adverbs can tell you where, when, how, why and to what extent something happens.

There are several different classes of adverb (see above).

They are often formed from adjectives or nouns be adding the suffix -ly.

For example: Quick becomes quickly, sudden becomes suddenly, intelligent becomes intelligently.

To form an adverb from adjectives ending in -y change the y to i before adding the -ly.

For example: angry becomes angrily, busy becomes busily.

To form an adverb from adjectives ending in -e drop the -e before adding the -ly.

For example: feeble becomes feebly, true becomes truly.

Some adjectives ending in -ly need no changes.

For example: heavenly.

However there are exceptions.

For example: sly becomes slyly, shy becomes shyly.

Some adverbs do not end in -ly.

For example: fast, hard, straight.
