Etymology

Origin of unwary

First recorded in 1570–80; un- 1 + wary

Explanation

Someone who's unwary isn't careful — in fact, an unwary person might be a little bit reckless. When your unwary cousin travels to China, he might end up being overcharged for a rickshaw ride. When you don't know the potential dangers or challenges that lie in front of you, you're unwary. While unwary people aren't overly suspicious or cautious, they run the risk of being taken advantage of or even getting hurt. To be wary is to be very watchful or cautious — it comes from the Old English root wær, "prudent, aware, or alert," and unwary combines it with un, or "not."
