Ersatz

Etymology

Ersatz (German:) is a German word meaning 'substitute' or 'replacement'. Although it is used as an adjective in English, it is a noun in German. In German orthography noun phrases formed are usually represented as a single word, forming compound nouns such as Ersatzteile ("spare parts") or Ersatzspieler ("substitute player"). While ersatz in English generally means that the substitution is of unsatisfactory or inferior quality compared with the "real thing", in German, there is no such implication: e.g., Ersatzteile 'spare parts' is a technical expression without any implication about quality, Kaffeeersatz 'coffee substitute' is a drink from something other than coffee beans, and Ersatzzug 'replacement train' performs a comparable service. The term for inferior substitute in German would be Surrogat, which is cognate to the English word "surrogate".
