Nouns – Invariant Plural


Nouns refer to a person, place, thing, event, substance or quality. {see Nouns, A1 Level}

Invariant Nouns are nouns which do not change in plural because they have a non-marked number.

The most common Invariant Plural Nouns are: Scissors, series, goggles, jeans, trousers, etc.

  • Your scissors are on the office desk.
  • This advertisement is about a new series.
  • These goggles cost a fortune!

Generally if we wish to change a word from being singular to being plural we just add “-s” to the singular. Invariant Nouns are the same in singular and plural, in that case we don’t have to add that termination (if they have a singular form).

When it has both singular and plural the article is adapted to it.

Invariant Nouns are nouns which do not change in plural. There are many invariant nouns in the English language but the most common ones are: Scissors, series, goggles, jeans, trousers, etc.

For example:
— “I bought a pair of jeans.” = Singular.
— “I bought two pairs of jeans.” = Plural.

NOTE: These nouns are the same in both singular and plural (if they have a singular form), if they are both, we need to use the correct article.
