A cowboy hat, especially one with a high rounded crown.
A wide-brimmed felt hat with a high, round crown, originally worn by American cowboys.
A large cowboy hat, not holding ten gallons like the name would suggest but usually around three quarts.
Origin of ten-gallon-hat
- Perhaps from Spanish galón braid, galloon (wrapped in rows above the brim) from French galon galloon
From American Heritage Dictionary of the English Language, 5th Edition
- Not certain. An earlier form without the number, gallon hat, comes by folk etymology from the Spanish galÃ³n ('braid'). It may also be a hyperbolic reference to the size of the hat, or a combination of the two.
