We make the present continuous tense by adding -ing to the base verb. Normally it's simple - we just add -ing. But sometimes we have to change the word a little. Perhaps we double the last letter, or we drop a letter. Here are the rules to help you know how to spell the present continuous tense.
Basic rule | Just add -ing to the base verb: | ||||||||||
work | > | working | |||||||||
play | > | playing | |||||||||
assist | > | assisting | |||||||||
see | > | seeing | |||||||||
be | > | being | |||||||||
Exception 1 | If the base verb ends in consonant + stressed vowel + consonant, double the last letter:
| ||||||||||
stop | > | stopping | |||||||||
run | > | running | |||||||||
begin | > | beginning | |||||||||
Note that this exception does not apply when the last syllable of the base verb is not stressed: | |||||||||||
open | > | opening | |||||||||
Exception 2 | If the base verb ends in ie, change the ie to y: | ||||||||||
lie | > | lying | |||||||||
die | > | dying | |||||||||
Exception 3 | If the base verb ends in vowel + consonant + e, omit the e: | ||||||||||
come | > | coming | |||||||||
mistake | > | mistaking |
