In Lower German, Norwegian and Swedish (at least), "lake" means "brine", as in pickling liquid. E.g. "saltlake" means specifically a brine that has a lot of salt. And this again comes from "lake" as in "body of water". Curious if the etymology that lake is coming via the French "lacquer" is actually the correct one, when the alternative that is coming from proto-Germanic "laki" is much closer to the actual chemical composition and way of preparation of the dye lake?
