Irregular Plural Nouns. Definition, examples and Exercise.

By | July 26, 2017

Irregular nouns form plurals in unusual ways. Dictionaries will give you the plural spelling if it is irregular.

One person   =>   two people

One goose   =>   two geese

One louse   =>   two lice

One mouse   =>   two lice

Some nouns are spelled the same way whether they are singular or plural.

One cod   =>   two cod

One quail   =>   two quail

One fish   =>   two fish

Nouns with Latin and Greek origins form plurals in strange ways. Because Latin and Greek plural endings are so unusual, many people try to follow the English rules by adding s or es. Applying the English rules is acceptable for some nouns, but using the original spelling is usually better. You will notice in the chart below that nouns with the same endings form plurals in the same way every time. Impress your friends and family by knowing the correct forms.

-a => -ae us => -i -is => -es -on -a and -ie -ce
Alga => algae Radius => radii Basis => bases Zoon => zoa
Larva => larvae Stimulus => stimuli Thesis => theses Automaton => automata
Nebula => nebulae Syllabus => syllabi Ellipsis => ellipsis Polyherdon => polyherda
Focus => foci Oasis => oases Ortacerdon => ortahedra
Synthesis => syntheses

 

Some nouns exist only in the plural form.

Customs                     Earnings

Fireworks                   Goods

Funds                          Guts

Manners                     Wages

Drawers                      Odds

Note: This is not a complete list.

Hint: Many people think that you have to use an apostrophe + s when making years plural, but most style guides actually suggest that you leave out the apostrophe.

The Industrial Revolution took place between the late 1700s and early 1800s. I was born in the ’90s. (Notice how the apostrophe in ’90s comes before the number. That’s because the apostrophe is being used to replace the 19 in 1990s. It has nothing to do with whether the number is plural or not.)
