| G. The doubling of consonants
1. When we add ed, ing, er or est to a word, we sometimes double a final consonant. This happens when a one-syllable word ends with one vowel and one consonant, e.g. stop, get, thin, sad.
stop → stopped get → getting
thin → thinner sad → saddest
2. We do not double y, w or x.
play → played new → newest
fax → faxing
We do not double when there are two consonants.
ask→ asking short → shortest
rich → richer
And we do not double when there are two vowels.
seem → seemed shout → shouting
fair → fairest
3. the rule about doubling is also true words of more than one syllable (e. g. permit = per + mit), but only if last syllable is stressed.
Per`mit → per`mitted
Pre`fer → pre`ferring
We do not usually double a consonant when the syllable is unstressed.
`open →opened `enter → entering
An exception is that in British English l is usually doubled, even if syllable is unstressed.
Travel → traveled (US: traveled)
