Adverbs are usually formed by adding ‘-ly’ to an adjective. Adjectives that end in -ly, such as Lovely or lonely, can’t be made into adverbs by adding -ly. Here are some tips to help you form adverbs and spell them correctly.

The basic rule is that -ly is added to the end of the adjective:
adjective                               adverb
quick                                       quickly
sudden                                    suddenly
straightforward                     straightforwardly

If the adjective has two syllables and ends in -y, then you need to replace
the final -y with -ily:
adjective                                             adverb
happy                                                    happily
hungry                                                  hungrily
lazy                                                       lazily

If the adjective ends with a consonant followed by -le, replace the final -e
with -y on its own:
adjective                                              adverb
terrible                                                   terribly
comfortable                                        comfortably
incredible                                              incredibly


Adverbs are usually formed by adding ‘-ly’ to an adjective.

For example:

  • quiet – quietly
  • careful – carefully
  • careless – carelessly

Adjectives ending in ‘-le’ change to ‘-ly’.

For example:

  • possible – possibly
  • probable – probably
  • incredible – incredibly

Adjectives ending in ‘-y’ change to ‘-ily’.

For example:

  • lucky – luckily
  • happy – happily
  • angry – angrily

Adjectives ending in ‘-ic’ change to ‘-ically’.

For example:

  • basic – basically
  • ironic – ironically
  • scientific – scientifically

Some adjectives are irregular. The most common irregular adverbs are:

  • good – well
  • hard – hard
  • fast -fast
