7. Doubling Final Consonant—Words of More Than One Syllable. If a word has

more than one syllable and the accent is on the last syllable, the same rule applies

as for a one-syllable word.

commit + ed = committed

(The accent is on the last syllable t is doubled.)

control + ing = controlling

equip + ed = equipped

propel + er = propeller

What happens if the word is not accented on the last syllable?

refer + ence = reference

(The accent is not on er; r is not doubled.)
