- bronco
- (Sp. model spelled same [bróŋko], of uncertain origin; may be from Latin broncus, via broccus 'having long, uneven teeth' as the DRAE concludes; or from an early Spanish term meaning originally 'piece of a cut branch' or 'knot in wood' < Vulgar Latin *bruncus, a cross between broccus 'pointed object' and truncus 'trunk' as Corominas hypothesizes)Clark: 1850s. Hendrickson, Clark, and Blevins all reference this term.1) Originally applied to a wild or unbroken horse. It could be used as an alternate term for mustang. It was later applied more loosely to any unmanageable or vicious horse. More recently, the term refers to any horse used by a cowboy.2) The term could also be an adjective describing an unruly horse or a wild, rebellious person. The DRAE references the adjective bronco, meaning crude, rough, or unrefined, and also mentions a noun form used in Mexico meaning an untamed horse. Santamaría concurs, describing a bronco as a horse that has not yet been broken and therefore fights the reins and rider.Alternate forms: bronc, bronch, broncho.Cowboys came to prefer the anglicized form bronc.
