Suffixes. Are we supposed to double the consonant at the end of a verb when we add -ed or -ing? In the United States, the answer depends on the sound of the word.*
When the pronunciation accent is on the first syllable, add a plain old -ed or -ing to the verb. No doubling.
Cancel (pronounced CAN-cel) becomes canceled or canceling. Cancellation has two Ls because the pronunciation is cancel-LAY-shun.
Benefit (BEN-e-fit): benefited, benefiting
Bicker (BICK-er): bickered, bickering
Happen (HAP-pen): happened, happening
Profit (PROF-it): profited, profiting
Quarrel (QUAR-rel): quarreled, quarreling
Travel (TRA-vel): traveled, traveling
Visit (VIS-it): visited, visiting
When a verb has more than one syllable, the final consonant is doubled when the accent is on the last syllable.
Admit ("ad-MIT"): admitted, admitting
Commit ("com-MIT"): committed, committing
Confer ("con-FER"): conferred, conferring
Occur ("oc-CUR"): occurred, occurring
Prefer ("pre-FER"): preferred, preferring
*While there are surely exceptions, this rule applies to verbs ending in consonant-vowel-consonant (travel, e.g., ends in v-e-l), not verbs ending in vowel-vowel-consonant (remain, e.g., ends in a-i-n, which would make the spelling remained, remaining).
