To make continuous verbs add -ing to the base verb:
do becomes doing
ask becomes asking
When the verb ends with a silent e, drop the e and add -ing:
make becomes making
take becomes taking
For short, one-syllable verbs, that end with consonant + vowel + consonant (CVC), we must double the last consonant and then add -ing:
swim becomes swimming
run becomes running
For words that end w, x and y, do not double the last consonant; just add -ing:
enjoy becomes enjoying
study becomes studying
When words have two or more syllables ending in CVC, you must double the last consonant if the last syllable is stressed. When the last syllable is not stressed, just add -ing.
The last syllable is stressed:
commit becomes committing
The last syllable is not stressed:
whisper becomes whispering
For verbs that end in -ie, change the ie to y before adding -ing:
die becomes dying
