unvertretbare

Unvertretbare is a German adjective used to describe something that cannot be substituted or defended. In one sense, it refers to objects, values, or conditions whose unique characteristics or fundamental importance cannot be replaced by alternatives. In another sense, it denotes an argument, position, or claim that is indefensible or unacceptable under certain standards.

Etymology: The word combines the prefix un- with vertretbar (substitutable or defendable), from vertreten (to represent or to defend). Thus unvertretbar literally means “not defensible” or “not substitutable.” The feminine form is unvertretbare and it declines like a regular adjective (for example, eine unvertretbare Forderung, der unvertretbare Gedanke).

Usage: The term appears mainly in formal, philosophical, political, or ethical discourse. It is often used to describe a demand, position, or policy deemed indefensible, or a value considered irreducible or non-substitutable in a given context. Example sentences: Die Forderung ist unvertretbar, sie widersetzt sich grundlegenden Prinzipien. Aus ethischer Sicht kann dieses Handeln unvertretbar sein.
