Spelling of verbs in the Present Progressive
Adding -ing in the Present Progressive
Be careful with some words when adding -ing to the infinitive.
1. consonant after a short, stressed vowel at the end of the word
Double the consonant.
sit – he is sitting
put – he is putting
If the vowel is not stressed, we do not double the consonant:
benefit – benefiting (Here we stress the first -e, not the -i.)
In British English we double one -l at the end of the word:
travel – travelling
2. one -e at the end of the word
Drop the -e.
write – he is writing
take – he is taking
double-e: Add -ing:
see – he is seeing
3. verbs ending in -ie
Change -ie to -y.
lie – he is lying
4. verbs ending in -c
Change -c to -ck.
picnic – he is picnicking
