The following words have roots with one syllable. To each, the - ing suffix has been added. Which word is spelled correctly?

A. Shiping

B. Hiting

C. Meeting

D. Triming

When a word ia a monosyllable ending with a consonant and preceded by one vowel, the last consonant has to be doubled before adding a suffix that begins with a vowel Ex, ship + p + ing = shipping

hit + t + ing = hitting

trim + m + ing = trimming

When the last consonant is preceded by 2 vowels, then it doesn't double. Just add 'ing' meet + ing = meeting

wait + ing = waiting

The correctly spelled Word is meeting. All of the other words need a double consonant. So we need : shipping trimming and hitting. You know that a word needs a double consonant in the gerund form if it has a short vowel.
