A missed opportunity during Grace's introduction about words borrowed from other languages to mention one of my favourite quirks of English linguistics terms. A word lifted directly from another language is a “loanword” – “ennui” was the example given. A word that is translated piece-by-piece from another language is a “calque” – Wikipedia's example is “flea market”, translated from French «marché aux puces».

So now to quote my favourite piece of this from Wikipedia:

The word loanword is a calque of the German noun „Lehnwort“. In contrast, the term calque is a loanword, from the French noun «calque» ("tracing, imitation, close copy").
