How to form gerunds correctly

There are a few spelling rules that you need to know in order to form gerunds correctly. The spelling of a gerund depends on the vowels (a, e, i, o, u) and consonants (b, c, d etc.) at the end of the verb:

	If there is more than one consonant, just add ING:
think + ing thinking
	If there is more than one vowel, just add ING:
beat + ing beating
	If there is one vowel and one consonant, and the syllable is stressed, double the consonant and add ING:
hit + t + ing hitting
	If there are one or more consonants and E, remove the E and add ING:
take + ing taking
	In most other cases, just add ING:
study + ing studying
see + ing seeing
