2. * From Vulgar Latin *stagnicāre, from Latin stāgnum (“piece of standing water, pond; fen, swamp”), possibly from Proto-Indo-European *steh₂g- (“to drip; to seep”).
3. * From Vulgar Latin *stānticāre, from *stānticus (“tired”), from Latin stāns, stāntis (“standing; remaining, staying”). Stāns is the present active participle of stō (“to stand; to remain, stay”), ultimately from Proto-Indo-European *steh₂- (“to stand (up)”).
4. Etymology 2 sense 1.2 (“to make (a building or other structure) watertight or weatherproof”) is derived from French étancher (“to stop water from flowing, make watertight”), from Old French estanchier (verb): see above.
