Grammatically Correct: Nouns With Special Plural Forms

In the never ending quest to conquer learning a language there are always special situations one will encounter in leaning the vocabulary of the language and English is no exception.  Please note that the information provided is written using common English spelling and grammar in the United States and UK and other English speaking countries may use slightly different variances of the information provided here.

When learning the plural forms of nouns the simplest rule is to add just an “s” or “es”.  However there are some nouns that when converting to their plural form does not follow that rule. 

These nouns have what is called irregular plural forms and these plural forms are spelled differently.  There are also some nouns that singular and plural forms are spelled exactly the same.  There are also nouns that make use of their Latin heritage when forming their plural words. Now let’s take a look at some of these special situations.

• The following are examples of nouns that require different spelling for their singular and plural forms:

            Man becomes men
            Woman becomes women
            Child becomes children
            Mouse becomes mice
            Goose becomes geese
            Tooth becomes teeth
            Foot becomes feet

• Here are some examples of nouns that have the same singular and plural forms:

            Sheep (singular) and sheep (plural)
            Moose (singular) and moose (plural)
            Deer (singular) and deer (plural)
            Trout (singular) and trout (plural)

            Also most Sports Teams and Corporation Fall under this category
            Examples:
            San Antonio Spurs, New York Yankees (used for both singular and plural reference}
            Ford Motor Company, General Motors, IBM

• Nouns that maintain their Latin or Greek form in the plural

            Here are some examples:
            Nucleus becomes nuclei
            Syllabus becomes syllabi
            Fungus becomes fungi 
            Cactus becomes cacti (although cactuses is also acceptable)
            Index becomes indices (indexes is also acceptable)
            Appendix becomes appendices (appendixes is also acceptable)
