Singular and Plural Noun Conversion Rules

There are a few basic rules for converting singular nouns into plural nouns.

  • Rule 1: Add ‘s’ at the end of the singular noun to make it plural. For example, cat=>cats; bird=>birds; pen=>pens; egg=>eggs; nest=>nests.
  • Rule 2: For nouns that end in ‘s’, ‘ss’, ‘sh’, ‘ch’, ‘x’, or ‘z’ requires an ‘es’ at the end of the singular noun to convert it into plural. Words ending with ‘z’ needs one extra z before ‘es’. For example, bus=>buses; witch=>witches; quiz=>quizzes (extra z); beach=>beaches; box=>boxes.
    • However, when the ‘ch’ at the end sounds like ‘k’, only ‘s’ is added to make it a plural noun. For example, stomach=>stomachs.
  • Rule 3: Singular nouns ending in ‘f’ or ‘fe’ need ‘s’ to be added at the end. However, sometimes the ‘f’ is required to be changed to ‘v’. For example, safe=>safes; wife=>wives (f converted to v); roof=>roofs; shelf=>shelves. belief=>beliefs.
  • Rule 4: Singular nouns that end with ‘y’ need changing of ‘y’ to ‘i’ before adding ‘es’ to make it plural. For example, baby=>babies; story=>stories; trophy=>trophies.
    • However, when there is a vowel (a, e, i, o, u) before ‘y’ then simply add ‘s’ to make it a plural noun. For example, toy=>toys; key=>keys; bay=>bays.
    • Again, when the singular noun ending with ‘y’ represents some places or person, only ‘s’ is added at the end. For example, Chakraborty=>Chakrabortys;
  • Rule 5: Some singular nouns are the same in their plural noun forms. For example, fish; deer; sheep; etc.
  • Rule 6: Singular nouns those end in ‘o’ followed by a consonant, requires ‘es’ for making it a plural noun. For example; tomato=>tomatoes, potato=>potatoes.
    • However, there are exceptions like piano=>pianos; halo=>halos. Remember that for the singular noun volcano; both volcanos and volcanoes are correct as a plural noun.
    • When the singular nouns have a foreign origin, only ‘s’ is added at the end in its plural noun form. For example, avocado=>avocados; maestro=>maestros
    • If the singular noun ending in ‘o’ is followed by a vowel, simply add ‘s’ to form a plural noun. For example, studio=>studios; portfolio=>portfolios.
  • Rule 7: When the singular noun ends in ‘is’, the ‘is’ changes to ‘es’ in its plural noun form. For example; Ellipsis=>ellipses; Analysis=>analyses.
  • Rule 8: Singular nouns ending in ‘on’ end in ‘a’ in its plural conversion. For example; Criterion=>criteria; Phenomenon=>phenomena.
  • Rule 9: When the singular noun ends in ‘us’, the plural noun ends in ‘i’. For example; focus=>foci; cactus=>cacti.
  • Rule 10: For irregular nouns, there are no specific rules for conversion into plural form. So, it’s always preferable to learn these words by heart. For example; Man=>men; tooth=>teeth; person=>people; child;=children; foot=>feet; etc.
  • Rule 11: There are few nouns that only have a plural noun form. Examples-binoculars, scissors, glasses, jeans, sunglasses, pants, headphones, pajamas, etc.
  • Rule 12: Collective nouns that represent a group of nouns are always plural noun in form. Examples: crew, company, audience, team, public, etc.
  • Rule 13: In a similar way, Some nouns are always in singular noun form even though they have ‘s’ at their end. Example; Maths, Physics, Classics, Aerobics, etc.
  • Rule 14: Singular Nouns with ‘um’ at their end need replacement of ‘um’ by ‘a’ in their plural noun forms. For example, datum=>data; curriculum=>curricula; medium=>media.
  • Rule 15: Few singular nouns that end with ‘a’, required changing of this ‘a’ by ‘ae’ for converting into the plural. For example, antenna=>antennae; alumna=> antennae.
  • Rule 16: For some singular nouns ending with ‘ex’ or ‘ix’, replace it with ‘ices’ while converting into a plural noun. For example, index=>Indices; appendix=>appendices.

Manasi Dey

Well, I am a Science Graduate, currently a housewife and mother of two. While helping my kids with their studies I find that schools are providing very few worksheets for practice at home which is not sufficient for the kids to think beyond the boundary. For better development and depth on each subject students should practice more and more worksheets or question papers. I am sure other parents also experienced the same problem. So through this website, I plan to provide various worksheets on different subjects to help interested kids, parents, and teachers.
