Plural Nouns (Regular, Irregular & Foreign)
One noun, two nouns — learn the regular pattern, the common irregulars, and the borrowed foreign plurals that trip learners up.
Grammar › Nouns › Plural Nouns (Regular, Irregular & Foreign)
The rule in one sentenceAdd -s to most nouns to make them plural (film → films) — but a small set of common and foreign nouns change form completely (woman → women, criterion → criteria) and simply have to be learned.
Singular to plural: the basic pattern
Most English nouns form the plural in the simplest way possible: add -s to the end. Ratcatcher premiered at the Cannes Film Festival in 1999, one of many British films selected that year, and Marvel Studios has released more than thirty films in its shared universe. That single rule covers the vast majority of nouns you will ever use.
A smaller group needs a spelling adjustment because of how the word sounds. Sunshine on Leith weaves several Proclaimers songs into the intertwining stories of two soldiers returning home to Edinburgh; notice that story becomes stories, not storys. These spelling changes follow pronunciation, not meaning.
Then there is a small, fixed set of very common nouns that don’t add anything at all — the whole word changes. Comfort and Joy and The Lavender Hill Mob are two much-loved British comedies enjoyed by women and men across generations, and Pride and Prejudice follows five sisters as they navigate love and family life. Woman becomes women and child becomes children; there is no shortcut, these simply have to be memorised.
Finally, English has borrowed plenty of nouns from Latin and Greek, and some of them kept their original plural endings. Critics often judge Morvern Callar against certain criteria, and Barbenheimer became one of the biggest phenomena in cinema history in the summer of 2023 — criteria and phenomena are already plural, so they never take an extra -s.
🎬 Compare: “One Marvel movie, two Marvel movies” (regular — just add -s) vs. “One woman, two women” (irregular — the whole word changes, it doesn’t just take -s) — the same kind of shift you’ll meet across British cinema, from The Lavender Hill Mob to Comfort and Joy.
Both are plurals, but only one of them follows a predictable rule.
How to build the plural
Regular plurals — just add -s
Ratcatcher screened at festivals around the world after its Cannes debut in 1999.
Marvel Studios has released more than thirty films in its shared universe.
Spelling changes: -es, -ies, -ves
Words ending -s, -sh, -ch, -x or -z add -es: Glenn Close is one of the most nominated actresses in Oscar history.
Words ending consonant + y change to -ies: Kathleen Kennedy has produced several successful trilogies.
Some words ending -f or -fe change to -ves: The Curious Case of Benjamin Button follows two very different lives.
Irregular plurals — the whole word changes
Comfort and Joy and The Lavender Hill Mob are enjoyed by women and men in equal measure.
Pride and Prejudice follows five sisters as they navigate love and family life as children become adults.
Foreign plurals — borrowed from Latin & Greek
The paparazzi surrounded the cast of Anatomy of a Fall at the Cannes Film Festival.
Barbenheimer became one of the biggest phenomena in cinema history in 2023.
Which pattern applies?
Use the regular pattern when…
- The noun is one of the thousands of ordinary English nouns: sequel → sequels, franchise → franchises.
- A word has settled into everyday film talk: fans simply say Terminator movies, not an irregular form.
- You’re pluralising a compound noun’s main word: the Underworld spin-offs.
Use an irregular or foreign plural when…
- The noun belongs to a small, fixed set that changes completely: The Addams Family follows two very different children.
- You’re using formal vocabulary common in film criticism: critics judge Shallow Grave against certain criteria.
- A collective noun like cast or crew is treated as a group of individuals rather than one unit — more common in British English (see the note below).
Words that call for a plural
Certain words can only be followed by a plural noun — they’re a reliable signal.

Common mistakes
❌ Both mans in American Hustle were nominated for an Oscar.
✅ Both men in American Hustle were nominated for an Oscar.
Man is irregular — the plural is men, not mans.
❌ Critics use different criterias to judge a Pixar film.
✅ Critics use different criteria to judge a Pixar film.
Criteria is already the plural of criterion — never add a second -s.
❌ The Resident Evil franchise has released ten movie.
✅ The Resident Evil franchise has released ten movies.
Any number above one needs the plural form of the noun.
❌ The Oscar’s went to Restless Natives.
✅ The Oscars went to Restless Natives.
This is a simple plural, not a possessive — no apostrophe is needed.
British vs American note: British English often treats collective nouns like cast or crew as plural — The cast of The Virgin Suicides are thrilled about the premiere — while American English usually keeps them singular: The cast of The Virgin Suicides is thrilled about the premiere. Both are correct in their home countries.
Exceptions & tricky cases
1. Invariable nouns never change. Some nouns look identical in the singular and the plural.
✅ One John Wick film, four John Wick films — but one series, two series: the Expendables series and the John Wick series use the same word either way.
2. Some foreign plurals keep their original ending. Phenomenon becomes phenomena, not “phenomenons” — Barbenheimer was one of the strangest box-office phenomena of the decade.
3. Some nouns only exist in the plural. You can’t say “a credit” to mean one item in a film’s list of names — the end credits of Passport to Pimlico list its large ensemble cast of London residents. Genevieve’s earnings made it one of the most profitable British comedies of the 1950s; there’s no singular “an earning”.
4. Decades take -s, never an apostrophe. Pulp Fiction is a defining film of the 1990s, and Miracle in Cell No. 7 became a huge box-office hit in the 2010s.
