Furtive has a shadowy history. It may have slipped into English directly from the Latin furtivus or it may have covered its tracks by arriving via the French furtif. We aren't even sure how long it has been a part of the English language. The earliest known written uses of furtive are from the early 1600s, but the derived furtively appears in written form as far back as 1490, suggesting that furtive may have been lurking about for a while. However furtive got into English, its root is the Latin fur, which is related to, and may come from, the Greek phōr (both words mean "thief"). When first used in English, furtive meant "done by stealth," and later also came to mean, less commonly, "stolen." Whichever meaning you choose, the elusive ancestry is particularly fitting, since a thief must be furtive to avoid getting caught in the act.
