Adverb Form

We make many adverbs by adding -ly to an adjective, for example:

There are some basic rules about spelling for -ly adverbs. See the table below:

Adjective ending	do this	adjective	adverb
most adjectives	add -ly	quick nice sole careful	quickly nicely solely carefully
-able or -ible	change -e to -y	regrettable horrible	regrettably horribly
-y	change -y to -ily	happy	happily
-ic	change -ic to -ically	economic	economically

But not all words that end in -ly are adverbs. The words friendly, lovely, lonely and neighbourly, for example, are all adjectives.

And some adverbs have no particular form. Look at these examples:

Note that the form of an adverb can also change to make it comparative or superlative.
