Plurals

Plural forms vary significantly across languages, going far beyond the simple singular/plural distinction in English.

Languages like Arabic have six different plural forms based on quantity (zero, one, two, few, many, other), while some Asian languages like Japanese or Chinese don’t pluralize nouns at all. Other languages like Russian or Polish use different forms based on the last digit of the number.

These differences matter tremendously for localization because using incorrect plural forms makes your software feel unprofessional or even confusing to users.

When a Polish user sees “5 wiadomość” instead of “5 wiadomości,” it’s immediately apparent that the software wasn’t properly localized. Proper plural handling is one of those subtle details that separates professionally localized software from amateur attempts.

Localazy follows the CLDR standard of pluralization rules, and provides you with an interface to correctly provide all plural forms needed for the target language.

The system automatically checks that all required plural forms have been provided for each language and ensures that variables and placeholders are consistently used across all plural variants — preventing runtime crashes due to missing placeholders.

For example, if a translator completes the “one” form but forgets the “other” form for a language, Localazy will flag this as incomplete.

This proactive validation approach means your applications will display correct plural forms across all languages.

Yes, Localazy’s Professional tier and above gives you access to custom plural rules per language.

While Localazy follows CLDR standards by default (which works with most i18n libraries), some frameworks or custom implementations might require specific plural handling. Through the Developer Console, you can modify which plural categories should be available for each language in your project.

This customization ensures perfect compatibility with any i18n framework you’re using. You can enable or disable specific plural categories (zero, one, two, few, many, other) for each language, ensuring that Localazy exports exactly the plural structure your application expects.

While it might seem straightforward to code singular and plural forms with a simple if/else statement in English, this approach quickly falls apart when dealing with other languages. Different languages have drastically different rules for plurals - English only differentiates between one and many, but languages like Czech and Polish require different forms for 1, 2-4, and 5+ items, while Arabic has six different plural forms depending on the count.

Even seemingly simple cases get complex quickly. Russian changes forms based on the last digit of the number, except when the second-to-last digit is 1. These complexities mean that hardcoding plural logic creates a maintenance nightmare with nested conditions that break easily when adding new languages.

Building and maintaining these linguistic rules yourself essentially requires becoming an expert in dozens of language grammars rather than focusing on your core product. When expanding to new markets, you’d need to rewrite parts of your app for each language’s plural system, potentially delaying your international launches. Using a proper localization system that handles these rules automatically is both faster and more reliable.
