[Alneyan]

Piquant:
1. Spicy.
2. Appealingly provocative.
3 Charming, interesting, or attractive.
4. Archaic: Causing hurt feelings; stinging.

Being fairly lazy, the above definition comes straigth from the trusted dictionary. For once, a French word has almost kept the same meaning in English and the same spelling (well, expect that the fourth meaning is the most common in French; is it really archaic?).

Oh, and what about creating words as well? For example, wouldn't "gabegie" be a nice-looking word for English? It means "turmoil or various trouble, especially due to a mismanagement" in French, but you could probably broaden its meaning a bit.

Let's see: "The word "Gabegie" was the only one fitting to describe the situation at the office after his blunder." Hmm... It is perhaps not such a great idea.
