Can you give an example of plural forms?

There are two types of plural nouns in English: regularand irregular.

A regular plural noun is formed by adding an "s" or an "es" to the end of the noun.

An irregular plural noun is formed in some other way.

The majority of nouns simply add an "s" to the end of the noun. For example:

• Apple > Apples
• book > books
• cat > cats
• daughter > daughters
• egg > eggs

If a Word ends in s, x, ch, sh add "es" to the end. For example:

• moss > mosses
• box > boxes
• bus > buses
• church > churches
• bush > bushes

One exception to this rule, is if the ch ending is pronounced with a "k" sound, you add "s" rather than "es":

• stomach > stomachs
• epoch > epochs

If a Word ends in z add "zes" to the end. For example:

• quiz > quizzes
• buzz > buzzes

If a Word ending in y is preceded by a vowel add "s". For example:

• essay > essays
• valley > valleys

The following are examples of irregular plural nouns.

If a Word ending in y is preceded by a consonant change the y to "ies". For example:

• country > countries
• secretary > secretaries
• reply > replies

If a Word ends with f or fe (but not ff or ffe) change the f or fe to "ves". For example:

• knife > knives
• shelf > shelves
• wolf > wolves

Some nouns have irregular plural forms that don't end in s. For example:

• die > dice
• man > men
• child > children
• mouse > mice
• foot > feet

Some nouns have the same form whether singular or plural. For example:

• deer > deer
• offspring > offspring
• salmon > salmon
• sheep > sheep

Some nouns have unusual plural forms that are derived from other languages. For example:

• cactus > cacti
• datum > data
• medium > media
• graffito > graffiti
• oasis > oases
