Here's a newsletter about words, the origin of them, I mean. I'm enjoying the current issue, which explains how "flotsam and jetsam" are actually legal terms for material lost off cargo ships, and there are two other categories, and they indicate whether you can legally scavenge them, which would be useful, no?
