Quando dobramos as consoantes finais?

WHEN WE DOUBLE CONSONANTS

We double the final consonant before EST, ER, ED and ING when the word ends in CONSONANT - VOWEL - CONSONANT.
E.g.: stop / stopping - plan / planning - rob / robber - hot / hottest - thin / thinner, etc.

If the word has more than 1 syllable we double that final consonant only if the final syllable is stressed.
E.g.: permit / permitted - prefer / preferring - begin / beginning, etc.

If the final syllable is not stressed we don’t double the final consonant.
E.g.: visit / visiting - listen / listened - remember / remembered, etc.

(If the final syllable is not stressed and the last consonant is L, the consonant may be single or doubled.
E.g.: cancel / canceling or cancelling - travel / traveling or traveling, etc.)
