To form the gerund of an English verb, just add the ending -ing to the
infinitive, without having to modify the spelling of the word. If the
infinitive ends in -e, it is necessary to remove this vowel before adding
-ing. In the case of -ee, -oe or -ye, the e is maintained. In words with a
short pronunciation vowel before a final consonant, the final
consonant is doubled. This is not the case with the final consonants -w,
-y, or -x. Verbs ending in -ie replace these vowels with one and before
adding the ending -ing.
