Plural form of nouns- The form of a word (noun) used to indicate that there are multiples is known as a plural word or noun. Most nouns can be made plural by simply adding -s or -es to the end.
Depending on what letter a noun finishes in, pluralization rules can vary greatly. Irregular nouns must be learned or looked up in a dictionary because they do not adhere to the plural noun rules.
Steps of Pluralization of a noun are as follows-
Add 's' to the end of normal nouns to make them plural.
Add the letter "es" to the end of the single noun if it ends in s, ss, sh, ch, x, or z to make it plural.
Some singular nouns with -s or -z endings need to have the -s or -z doubled before the -es is added to make them plural.
If the noun ends in f or fe, the f is frequently altered to -ve before the -s is added to create the plural form.
If the letter before the -y in a singular noun ends in y, modify the ending to ies to make the noun multiple.
