​What are Regular Plural nouns ?

Regular plural nouns are the ones that end in "s" and "es".
Examples: Oceans, donkeys, institutions,
matches, buses, benches, etc.

​Convert regular plural nouns to singular

For converting regular singular nouns into plural, we simply add "s" or "es".
Therefore, converting regular plural nouns to singular simply requires the deletion of "s" or "es" from the noun.

Examples:
Markers x---> Marker
Brushes x---> Brush

What are compound plural nouns?

Nouns formed by the combination of nouns, prepositions, verbs or adjectives are called compound nouns, and when they are written in their plural forms, they are called Plural Compound nouns.


Examples: Mothers-in-law, Toothbrushes, etc...

​Convert plural compound nouns to
singular

• Plural compound nouns are formed by the addition of "s" or "es" to the principal word or noun.

• Therefore making plural compound nouns singular simply involves the removal of "s" or "es" from the nouns.

• Examples:

  Sunflowers x---> Sunflower
  Lunchboxes x ---> Lunchbox
  

Irregularities in Plural Noun Forms

• There are multiple nouns in English that do not follow the rule of "s" or "es" in plural.

• In such cases, they form plurals with other additions like "ves", "ies", "en", "i", "a", and much more.

• While turning such nouns to their singular forms, removing these endings and replacing the omitted letters like "y", "um", "f", is essential.

• Examples:
  Geese x ---> Goose
  Data x ---> Datum

• When such irregular nouns combine with other words to form compound nouns, the same rules of irregularity applies to the compound word as well.

• The word that is pluralized is changed to singular, keeping the other word untouched.

• Butterflies x ---> Butterfly
  Policemen x ---> Policeman
