Etymology: The French "merci" began as a noun meaning "mercy," the same word that gave English "mercy" itself. Over centuries in French, the plea for divine or royal clemency shrank into an expression of gratitude, so that saying "merci" came to mean something close to "I thank you." English borrowed the word in that later sense, keeping the French spelling and pronunciation, and it still sits in English as a near-doublet of "mercy," the two forms descending from the same Latin root but arriving by different routes. Because it is a borrowing, "merci" shows its foreignness in ways native English words do not. Its interjection use is the everyday one, while its noun use is rarer and tends to appear in phrases where the French flavour is deliberate. The word carries the old sense of grace or favour inside a single syllable of thanks, which is why it can sound both casual and faintly formal depending on who says it.
