Adding -ing/-ed

Adding -ing/-ed

Often we need to add -ing or -ed to a verb to make other forms of the verb, for example:
I was talking when John arrived.
Spelling Rule
Just add -ing or -ed to the end of the base verb:
  • work > working > worked
  • play > playing > played
  • open > opening > opened
Exceptions
If the base verb ends in:do this:and add:For example:
consonant + vowel + consonant
and a stressed syllable
double the final consonant-ing
-ed
stop > stopping > stopped
begin > beginning
tap > tapping > tapped
But, for example:
open > opening > opened
(because no stress on last syllable of open)
consonant + -eremove the -e-ing
-ed
phone > phoning > phoned
dance > dancing > danced
make > making
rake > raking > raked
-iechange the -ie to -y-inglie > lying
die > dying
nothing-dlie > lied
