3 When a verb ends in a consonant + y, the y changes to ies.
hurry --> hurries copy > copies We do not change y after a vowel. stay > stays enjoy > enjoys

hope > hoped save >saved

3 Sometimes we double a final consonant. This happens when a one-syllable verb ends with one vowel and one consonant, e.g. beg, plan.
beg > begged plan > planned For more details about doubling, see G.
D The ing-form
1 We normally leave out e when we add ing to a verb.
take > taking drive > driving But we keep a double e before ing.
see > seeing agree > agreeing
2 When a verb ends in ie, it changes to ying.
die > dying lie > lying But y does not change.
hurry > hurrying

E Adverbs
We form many adverbs from an adjective + ly. slow > slowly calm > calmly

probable > probably sensible > sensibly
4 When an adjective ends in ic, we add ally.
automatic > automatically romantic --> romantically But there is one exception. public > publicly
F The comparison of adjectives
We form the comparative and superlative of short adjectives with er and est. See Unit 110.
old > older, oldest
quick > quicker, quickest
1 If the adjective ends in e, we add r and st.
late > later, latest fine > finer, finest

big > bigger, biggest flat > flatter, flattest For more details about doubling, see G.
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 for words of more than one syllable (e.g. permit = per + mit), but only if the last syllable is stressed.
per'mit > per'mitted
prefer > preferring
We do not usually double a consonant when the syllable is unstressed.
'open > opened 'enter> entering An exception is that in British English 1 is usually doubled, even if the syllable is unstressed.
