Spelling rules for the formation of the present participle.
a. Verbs ending in a silent e
When a verb ends in a silent e, the silent e is dropped before the ending ing is added. For example: make - making
However, when a verb ends in an e which is not silent, the final e is not dropped before the ending ing is added. For example: to be- being to see- seeing
b. Verbs ending in ie When a verb ends in ie, the ie is changed to y before the ending ing is added. to die -dying to lie -lying
When a verb ends in y, no change is made before the ending is added. fly-flying
c. One-syllable verbs ending in a single consonant preceded by a single vowel.
Except in the case of the final consonants w, x and y, when a one-syllable verb ends in a single consonant preceded by a single vowel, the final consonant must be doubled before the ending ing is added. The reason for this is to reflect the fact that the pronunciation of the single vowel does not change when the ending ing is added. put-putting
d. Verbs of more than one syllable which end in a single consonant preceded by a single vowel.
When a verb of more than one syllable ends in a single consonant other than w, x or y preceded by a single vowel, the final consonant is doubled to form the present participle only when the last syllable of the verb is pronounced with the heaviest stress.
In these examples, the syllables pronounced with the heaviest stress are underlined. For example: to ex'pel- expelling to be'gin-beginning to o'ccur- occurring to o'mit-omitting
