In Finnish, kaksivuotias refers to a person who is two years old, and its plural nominative is kaksivuotiaat (two-year-olds). The genitive plural form, kaksivuotiaiden, marks that the word relates to or belongs to the two-year-olds.

Etymology-wise, kaksivuotias is a compound of kaksi “two” and vuotias, a suffix meaning “years old,” a common construction in Finnish for age descriptors. The form kaksivuotiaiden illustrates how Finnish creates a genitive plural from an adjective-like noun to indicate a relationship to the plural age-group.

Usage notes: Kaksivuotiaiden is primarily a grammatical form used in writing and formal speech to indicate possession or association with two-year-olds. It is not a standalone concept, but a flexible inflection that appears in contexts involving families, education, childcare, and demographic descriptions.
