Comparison of adverbs

Adverbs of manner describe how we do an action. They answer questions with "How ... ?". 

Most are formed by:

adding -ly to the adjective.

• She walks slowly.

lf the adjective ends in consonant +y, the y changes to an i and then adds -ly. happy > happily

• It all ended happily.

We can compare two actions using this structure:

more/less + adverb + than.

• She walks more slowly than her sister.

• I drive less carefully than my father.

We can show that two actions are done in the same way using this structure:

as+ adverb + as.

• She walks as slowly as her sister.
