fünffache

Fünffache is a German term that denotes fivefold or quintuple, describing a quantity that is five times as large as a reference value. It can function as a noun (das Fünffache) or as an adjective (fünffach) in combination with a noun. The concept is part of a family of multiplicative expressions such as ein-, zwei-, drei-, vier- und fünffach, which describe multiples of a base amount.

As a noun, das Fünffache refers to the fivefold amount itself. The plural form is die Fünffachen. Examples include: Das Fünffache des ursprünglichen Betrags ist erreicht. In mathematics and everyday language, one can also speak of the Fünffachen einer Zahl, meaning five times that number.

As an adjective, fünffach or the related form fünffache is used to describe a noun directly. Common usages include fünffache Steigerung (fivefold increase) or fünffache Kosten (fivefold costs). The form adapts to gender and number according to German grammar, for instance eine fünffache Erhöhung or fünf neue, fünffache Anteile in einem Vergleich.

In mathematics and science, the concept is used to denote a multiplicative factor of 5. For a quantity x, the fivefold amount is 5x, and “das Fünffache von x” equals 5x. It is related to other multiplicative terms such as Vielfache und Quintuple, and is often contrasted with “zweifach,” “dreifach,” or “fünffach” in technical contexts.
