Nouns that speak about objects you can count have two forms: the singular and the plural. This guide to the plural noun forms will help you understand how to make regular and irregular noun plurals. There are also irregular verb forms in English that need to be studied, as well as changes in the comparative and superlative forms that are very similar to the plural changes in noun forms. Regular Noun Plural Forms - Just Add 'S' For most nouns, just add 's' to the end of the noun. singular noun + s = plural noun computer -> computersbag -> bagsbook -> bookstable -> tableshouse -> housescar -> carsstudent -> studentsplace -> placesetc. Irregular Noun Plural Forms - Nouns Ending in Consonant + Y Nouns that end in a consonant + 'y' drop the 'y' and add 'ies' to the end of the noun. singular noun - y + ies = plural noun baby -> babiesparty -> partiespaddy -> paddieshobby -> hobbieslady -> ladiesferry -> ferriessherry -> sherriesdandy -> dandiesetc. Irregular Noun Plural Forms - Nouns Ending in SH, Ch, S, X, or Z For nouns that end in sh, ch, s, x, or z, add 'es' to the end of the word. singular noun ending in sh, ch, s, x or z + es = plural noun beach -> beachesbox -> boxeschurch -> churchesbuzz -> buzzesloss -> lossesfox -> foxeswatch -> watchesdress -> dressesetc. Irregular Noun Plural Forms - Nouns Ending in O Many nouns that end in 'o' proceeded by a consonant require an 'e' before 's' to be placed at the end of the word. Unfortunately, there are also nouns that end in 'o' that do not require changes. To begin with, here are examples of nouns that do need to change. singular noun ending in consonant 'o' + es = plural noun tomato -> tomatoeshero -> heroeszero -> zeroespotato -> potatoesecho -> echoesetc. Other nouns that that end in 'o' proceeded by a consonant DO NOT require an 'e' before 's' to be placed at the end of the word. Nouns ending in 'o' proceeded by a vowel do not change. kilo -> kilosradio -> radioslogo -> logospiano -> pianossolo -> soloscargo -> cargoshalo -> halosetc. Unfortunately, there is no clear rule as to when to add an 'es' or just 's'. These plurals need to be learnt on their own. Irregular Noun Plural Forms - Nouns Ending in LF Nouns ending in the consonant combination 'lf' drop the 'lf' and end in 'ves'. singular noun ending in consonant 'lf' - 'lf' + 'ves' = plural noun leaf -> leaveshalf -> halvesself -> selveswife -> wivesknife -> knivescalf -> calvesshelf -> shelveswolf -> wolvesetc. Irregular Noun Plural Forms - Different Spellings There are a number of irregular plurals that change spellings in different ways such as 'man' to 'men' and 'ouse' to 'ice' here are some of the most common: man -> menwoman -> womenchild -> childrenfoot -> feetperson -> peoplemouse -> micetooth -> teethdie -> diceetc. Animal Plurals There are many animals that have irregular plural forms. Some animals do not change when forming the plural. deer -> deerfish -> fishsheep -> sheeptrout -> troutsquid -> squid Other animals change form in the plural. mouse -> micegoose -> geeseox -> oxenlouse -> lice Irregular Noun Plural Forms - Nouns That Remain the Same in Singular and Plural Nouns that do not have a plural form are also known as uncountable or non-count nouns. These nouns include concepts, materials, liquids as well as others. concepts: advice, fun, honesty, information, ambition, etc.materials: steel, wood, plastic, stone, concrete, wool, etc.liquids: water, wine, beer, soda, oil, gasoline, etc. Still other nouns remain the same whether in the singular or plural. These nouns take the plural conjugation of tenses, but remain the same spelling. Here are some examples with sentences to indicate the difference between singular and plural usage. crossroads -> crossroads There is a crossroads at the end of this street.There are a number of crossroads between here and downtown. series -> series The new series about a robot is great.There are four new series on ABC this month.
