Etymology

Origin of stanch

First recorded in 1275–1325; Middle English stanchen, staunchen (verb) < Old French estanchier “to close, stop, slake (thirst),” from Vulgar Latin stanticāre (unattested), equivalent to Latin stant- (stem of stāns, present participle of stāre to stand ) + -icāre causative suffix

Explanation

Use the verb stanch to describe stopping a liquid from spreading. A bandage can stanch bleeding and thick towels can stanch the flow of water across the kitchen floor when you drop a full glass of water. The vowel sound in stanch most frequently sounds like on: "stonch." Stanch can also be pronounced to rhyme with branch. Though it's a verb mostly commonly associated with keeping blood from flowing from a wound, the origin is likely the Latin word stagnum, meaning "pond, pool." This word is related to stagnate, describing water that has no movement.
