The English language is funny. It has all of these rules and then for each rule, it has its exceptions aka irregulars. In the English language when a noun becomes plural you simply add an -s or -es, however, there are irregular plurals that do not follow that simple rule.
Some of the most common English nouns have an irregular plural form. For example, the plural form of fireman is firemen not firemans or child is children not childs.
Sadly there are many irregular plural nouns in the English language and you simply just have to memorize them. But luckily there are some common patterns that irregular plurals follow.
The Most Common Irregular Plurals
Example: Nouns ending in -f or -fe
In order to make a word ending in -f, or -fe plural simply change the f to a v and add -es. So the end should be -ves.
For example, the plural form of wife would-be wives. See the chart below for more examples
|Singular (-f, -fe)||Plural (-ves)|
Nouns That Change Their Vowels
In addition, there are some English words that change their vowels when the noun becomes plural.
For example, oo becomes ee or an becomes en.
|Singular||Plural (vowel change)|
Irregular Nouns That Change Spelling
Furthermore, there are some irregular plurals that change their spelling.
For example, the plural form of child is children. See the chart below for more examples.
Irregular Nouns That Stay the Same when Plural
There are a few irregular plurals in the English language that stay the same when they are singular or plural.
For example, one fish or two fish. There are 10 fish swimming in the aquarium.
|Singular/ Plural (no change)|
