📖 What does "der Dreißiger" mean?

The word der Dreißiger primarily has two meanings:

  1. A male person aged 30 to 39: Someone in their fourth decade of life. Example: Mein Nachbar ist ein typischer Dreißiger (My neighbor is a typical man in his thirties).
  2. The 1930s (often plural "die Dreißiger"): The decade from 1930 to 1939. Example: Die Mode der Dreißiger war elegant (The fashion of the thirties was elegant). In this context, it's mostly used in the plural (die Dreißiger), even when referring to the decade as a single unit. If explicitly referring to a male person from that decade, "der Dreißiger" could be used, but it's less common than the age reference.

🚨 Attention: For a female person of this age, you use die Dreißigerin.

💡 It's a *substantivized numeral* (derived from dreißig - thirty).

🗣️ How to use "der Dreißiger"?

Usage heavily depends on the context:

  • Age reference (person): Refers to a male person between 30 and 39. Often used somewhat casually or as a generalization. You can also say "Er ist in den Dreißigern" (He is in his thirties). Example: "Typisch Dreißiger, er kauft sich jetzt ein Motorrad." (Typical thirty-something, he's buying a motorcycle now.)
  • Decade (mostly plural "die Dreißiger"): Refers to the years 1930-1939. Frequently used in historical, cultural, or social contexts. Example: "Die Kunst der Dreißiger war vom Art déco beeinflusst." (The art of the thirties was influenced by Art Deco.)

⚠️ The meaning is usually clear from the context. If discussing history, it likely means the decade. If discussing a person, it means their age.

There's little risk of confusion, as the plural form "die Dreißiger" is dominant for the decade, while "der Dreißiger" primarily denotes the male person.

🧠 Mnemonics and Memory Aids

Article Mnemonic: For a *man* of this age, you need der (masculine article). Think: Der Mann (the man) is now a Dreißiger.

Meaning Mnemonic (Age): Dreißig sounds like 'dry sig(nal)' - maybe at thirty, the *signal* for peak youth feels a bit *dry*? So, der Dreißiger is a man around thirty.

Meaning Mnemonic (Decade): Think of the *three* zeros in 'thirty' (30) representing the decade 19*30*s. Die Dreißiger were the 1930s.

📜 Poem about being a Dreißiger

Der Zwanziger ist lang vorbei,
Die Jugendzeit, ade, ade!
Nun ist er hier, der Dreißiger,
Das Leben wird oft fleißiger.

Mal ernst, mal locker, mittendrin,
Suchst nach dem großen Lebenssinn.
Die Dreißiger, ein starkes Stück,
Auf dem Weg zum Glück!

(The twenties are long gone by,
The time of youth, goodbye, goodbye!
Now he is here, the thirty-something man,
Life often becomes a busier plan.)

(Sometimes serious, sometimes loose, right in between,
Searching for life's great meaning unseen.
The thirties, a strong phase to embrace,
On the road to happiness and grace!)

Doch auch ein Jahrzehnt, historisch kalt.

Mal einen Mann in seiner besten Wahl.

But also a decade, historically cold.

Sometimes a man in his prime, quite noble.)
