means Salt produced by evaporating seawater rather than mining it from underground deposits.

from Straightforward compound of 'sea' and 'salt' — no hidden trick here. The practice is ancient: humans have been evaporating seawater or boiling brine in shallow pans for thousands of years, long before anyone needed to put the word on a label. 'Salt' itself traces back through Old English 'sealt' to a very old Indo-European root, the same one that eventually gave Rome its soldiers a 'salarium' — a salt allowance, the ancestor of 'salary.' The recent twist isn't etymological but commercial: chemically, sea salt is almost entirely the same sodium chloride as mined table salt, just with trace minerals and a better publicist.
