Adverbs
Adverbs modify a verb, an adjective, or another adverb. 

An adverb tells more about a verb in the sentence.

• It rained hard.

An adverb describes more about an adjective in the sentence.

• Nature is really amazing!

An adverb modifies another adverb in the sentence.

• It rains very hard.
• Computers run much faster these days.
• I clean my room less frequently because I am busy.

Commonly, adjectives can be changed to adverbs by adding 'ly'.

• slow – slowly
• quick – quickly
• comfortable – comfortably
• loud – loudly
• clear – clearly

To change adjectives ending in 'y' into adverbs, change the 'y' to 'i' and add 'ly'.

• happy – happily
• easy – easily
