Review messages that display counts and check whether each target language gets the correct plural form. Replace simple number-and-text joins or singular/plural branches with Intl.PluralRules or ICU MessageFormat, which select wording according to language-specific rules.

Use when reviewing string concatenation involving counts, translation key lookups, or i18n library configurations to check whether plural forms are handled correctly for all target locales.

Pluralization rules vary dramatically across languages — what works as a simple singular/plural branch in English produces grammatically wrong output in Arabic, Russian, Polish, and dozens of other languages. Shipping incorrect plurals signals low translation quality and breaks trust with native speakers in target markets.
Find all places in this codebase where a count value is concatenated with a string or where only singular/plural branching is used, without Intl.PluralRules or ICU plural syntax.
Replace count string concatenation and binary singular/plural logic with Intl.PluralRules-based key selection or ICU MessageFormat plural syntax so that all CLDR plural categories are covered for every target locale.
Explain why languages have different numbers of plural forms, what CLDR plural categories are, and how Intl.PluralRules and ICU MessageFormat solve pluralization correctly across locales.
Review translation files and components that render counts. Flag any strings that concatenate a number with text, any ternary that picks only between "singular" and "plural", and any i18next or react-intl message that is missing plural keys required by the target locale.
