dertigjarige

Dertigjarige is a Dutch adjective meaning thirty-year-old. It is used to describe someone or something that is thirty years old. In everyday language, the more common noun for a person in that age range is dertiger, but dertigjarige is frequently used as a pre-nominal modifier before a noun, as in dertigjarige man, dertigjarige vrouw, or dertigjarige werknemer.

Formation and usage: The word combines dertig (thirty) andjarige, an adjective suffix that denotes age in years. It is used almost exclusively before a noun; predicative use with the verb is usually expressed as dertig jaar oud, rather than using dertigjarige on its own.

Other uses: The term also appears in historical contexts as part of proper names. The Thirty Years’ War is called the Dertigjarige Oorlog in Dutch, a major European conflict that lasted roughly from 1618 to 1648. In this title the adjective is capitalized as part of the proper noun.

See also: Dertiger is the more common term for a person in their thirties, used as a noun. In demographic or sociological language, dertigjarige can describe age groups and is inflected to match the noun it modifies (dertigjarige mannen, dertiger vrouwen, etc.). In general, dertigjarige conveys a formal or descriptive nuance and is widely understood across Dutch-speaking contexts.
