pluralized

Pluralized is the past participle form of the verb pluralize and can also function as an adjective meaning "made plural." The verb pluralize means to change a word to indicate more than one, or to assign a grammatical plural to a word. Etymology traces pluralize to the noun plural and the suffix -ize, with plural itself derived from Latin pluralis.

In grammar, pluralization is the process by which nouns, pronouns, or determiners are marked to show plurality. The past participle pluralized describes something that has undergone this process, for example: "The noun was pluralized" or "The pluralized form of mouse is mice."

English pluralization follows a mix of regular and irregular patterns. Regular forms typically add -s or -es (cat → cats; dish → dishes), while irregular plurals involve vowel change, consonant alternation, or suppletion (man → men; foot → feet). Some words have identical singular and plural forms, while others change in more complex ways. The term pluralized is commonly used to refer to the result of applying these rules.

Beyond grammar, pluralization is a major concern in software localization. Plural rules differ across languages and are implemented in libraries and frameworks to select the correct plural form for a given count. The concept of pluralized thus appears in linguistic descriptions as well as in data-driven text generation.
