R3 In most cases, the plural is written 's'.
hat => hats
tree => trees
R4 The plural is written 'es' after 'sh', 'ss', 'x', or 's', and it is pronounced /ɪz/.
bush => bushes
glass => glasses
box => boxes
bus => buses
The plural is also written 'es' and pronounced /ɪz/ after 'ch', when 'ch' is pronounced /ʧ/.
church => churches
match => matches
speech => speeches
R5 When the 's' follows one of the sounds /f/, /k/, /p/, /t/ or /Ɵ/, it is pronounced /s/.
belief => beliefs

cap => caps
pet => pets
moth => moths
R6 When the 's' follows one of the sounds /s/, /z/, or /ʤ/, it is pronounced /ɪz/.
service => services
prize => prizes
age => ages
R7 Some nouns which end with the sound /Ɵ/, for example 'mouth', have their plural forms pronounced as ending in /ðz/. With others, such as 'bath' and 'path' the pronunciation can be either /Ɵs/ or /ðz/. You may need to check the pronunciations of words like these in a Cobuild dictionary.
R8 In most other cases the 's' is pronounced /z/.
bottle => bottles

R9 With nouns which end in a consonant letter followed by 'y', you substitute 'ies' for 'y' to form the plural.

lady => ladies
opportunity => opportunities
With nouns which end in a vowel fetter followed by 'y', you just add 's' to form the plural.
boy => boys
day => days
valley => valleys
R10 There are a few nouns ending in 'f' or 'fe' where you form the plural by substituting 'ves' for 'f' or 'fe'.
calf => calves elf => elves half => halves knife => knives |

radio => radios
However, the following nouns ending in 'o' have plurals ending in 'oes':

The following nouns ending in 'o' have plurals which can end in either 's' or 'es':

R12 The following nouns in English have special plural forms, usually with different vowel sounds from their singular forms:
child => children foot => feet goose => geese |
louse => lice man => men mouse => mice |

R13 Most nouns which refer to people and which end with 'man', 'woman', or 'child' have plural forms ending with 'men', 'women', or 'children'.
postman => postmen
Englishman => Englishwomen
grandchild => grandchildren
R14 In addition to the nouns mentioned above, there are words which are borrowed from other languages, especially Latin, and which still form their plurals according to the rules of those languages. Many of them are technical or formal, and some are also used with a regular 's' or 'es' plural ending in non-technical or informal contexts. You may need to check these in a Cobuild dictionary.

nucleus => nuclei

R16 Some nouns ending in 'um' have plurals ending in 'a'.
