What does pluralisation mean?
Pluralisation is the process by which a word takes its plural form, or the system of rules governing that change in a particular language. In English, many regular nouns simply add -s, while others form their plurals by changing their endings: for example, child becomes children and leaf becomes leaves. The term may also refer to the resulting plural form itself, as when a speaker corrects another person’s pluralisation. Pluralisation is especially important in grammar, editing, language teaching and translation, where the conventions of a language must be applied consistently. Although many patterns are regular, some have historical exceptions, and usage can differ between English-speaking regions. The British spelling pluralisation follows the familiar -isation pattern, while American English normally uses pluralization.

Where does pluralisation come from?
Pluralisation is formed in English from the adjective plural and the suffix -isation, meaning the process of making or performing something. The adjective plural entered English through Old French from Latin pluralis, meaning “belonging to more than one” and ultimately derived from Latin plures, “more.” The same Latin root survives in English words such as plurality and pluralism.
