About Pluralize Words
English pluralization is irregular: 'cat' → 'cats' is easy, but 'child' → 'children', 'goose' → 'geese', 'criterion' → 'criteria' all break the basic rule. This tool uses the popular pluralize library, which contains exhaustive lists of irregular plurals and the rules for common patterns.
When to use it
- Pluralizing UI labels based on a count (1 item, 5 items)
- Generating grammatically correct messages programmatically
- Producing pluralized variants of vocabulary for content
How it works
Each word in the input is processed by the pluralize library. The library applies a hierarchy: irregular plurals first (child/children), then suffix-based rules (-y → -ies, -us → -i, etc.), then default 's' suffix.
Examples
cat child goose criterion
cats children geese criteria
Frequently asked questions
- Is the plural always correct?
- For common English vocabulary, yes. The pluralize library has thousands of irregular plurals built in. Rare or technical terms may need manual correction.
- What about non-English words?
- Only English is supported. Loanwords with English plurals (e.g. 'datum/data') work; native plurals of other languages (e.g. Italian 'paninos') don't.
