30er

30er is a informal German term used to describe a person who is in their thirties, typically aged between 30 and 39. It functions as a noun and is most common in everyday speech and popular media. The plural form is usually die 30er.

Etymology and usage variants: the word is formed from the numeral 30 plus the suffix -er, a pattern used in German to create stand-alone nouns that denote age or generation. In everyday language one might say “ein 30er” or “eine 30-Jährige” in more formal or written contexts, with the latter being the standard way to refer to a person aged 30 to 39 in neutral prose. The term is primarily gender-neutral in casual speech, but more formal or precise wording may use age-based descriptors such as 30-Jähriger or 30-Jährige.

Distinction from the decade and other meanings: in some contexts, 30er can be confused with references to the 1930s or to people born in the 1930s. For the decade, German typically uses die 1930er Jahre. When referring to birth cohorts, terms like der Jahrgang 1930er or der 1930er-Jahrgang are used to avoid ambiguity.

Context and relevance: 30er is commonly employed in marketing, demographics, youth and life-stage discussions, and in informal social discourse to characterize common experiences associated with being in one’s thirties, such as career development, family planning, or lifestyle choices. It is less common in formal writing, where more precise age ranges or demographic labels are preferred.
