How do you change plural nouns to singular nouns?

Answer 1

The plurals of most nouns are made by adding an 's'. e.g. apple/apples. And there are special cases and rules that come with different word endings, e.g. lady/ladies, potato/potatoes.

However, some singular nouns have irregular plurals . Because they are irregular, there is no rule for converting such nouns into their respective plural forms:

Some examples of nouns with irregular plurals:

• goose/geese
• sheep/sheep
• man/men
• mouse/mice
• person/people
• cactus/cacti

Answer 2

Often you add an s eg house becomes houses. goat = goats.

Some words are unusual because their plural is rather different.

So mouse becomes mice, die becomes dice, medium becomes media.

Answer 3

Add "s" or "es" to the end.

Examples: (singular -> plural)

• Apple -> apples.
• Menu -> Menus
• Frog -> frogs.
• Box -> boxes.
• Tomato -> tomatoes.

There are also many irregular nouns which have special plural forms, or where the plural noun is the same as the singular.

Examples: (singular -> plural)

• Mouse -> mice.
• Medium -> media.
• Deer -> deer.
• Species -> species.

Answer 4

A regular plural is a noun that has a plural ending in -s or -es. To make the plural singular, remove the ending -s or -es:

• birds to bird
• churches to church
• goats to goat
• lunches to lunch
• glasses to glass

There are too many forms of irregular plural to have a simple answer. A knowledge of irregular plurals or a dictionary are often the only simple way to change an irregular plural to its singular form or to know which plural is irregular or regular. Some examples are:

• heroes to hero
• tomatoes to tomato
• photos to photo
• tattoos to tattoo
• babies to baby
• ladies to lady
• boys to boy
• days to day
• calves to calf
• knives to knife
• wives to wife
• men to man
• feet to foot
• mice to mouse
• children to child
• bases to basis
• crises to crisis
• diagnoses to diagnosis
• media to medium
• data to datum
• formulae to formula
• axes to axis
• indeces to index
• stimuli to stimulus
