2. Doubling the final consonant
We saw in a previous point above that if a verb has two syllables and the second syllable is stressed, as well as if verbs ends in a vowel + l, we double the final consonant. However, there are other situations when we have to double the final consonant:
– Word ends in vowel + consonant + –ing/-ed/-er/-est:
stop → stopped, stopping, stopper
put → putting
big → bigger, biggest
run → runner, running
set → setter, setting
3. Possessive ‘s
Most nouns simply add an ’s to the noun.
flat → flat’s, cat → cat’s
The Exceptions are:
- Regular Plural nouns add only an ‘ (apostrophe)
- boys → boys’, cats → cats’, people → people’s
- Singular proper nouns (names) ending in –s can add ‘s or ‘
- Jones → Jones’s or Jones’, The Smiths → The Smiths’s or The Smiths’
- Irregular plural nouns (not ending in –s) add ‘s
- men → men’s, children → children’s
- Words like somebody, anybody, one, each other, add an ‘s
- one → one’s, somebody → somebody’s
