Old English horn "horn of an animal," also "wind instrument" (originally made from animal horns), from Proto-Germanic *hurnaz (cf. German Horn, Dutch horen, Gothic haurn), from PIE *ker- "horn; head, uppermost part of the body," with derivatives refering to horned animals, horn-shaped objects and projecting parts (cf. Greek karnon "horn," Latin cornu "horn," Sanskrit srngam "horn," Persian sar "head," Avestan sarah- "head," Greek koryphe "head," Latin cervus "deer," Welsh carw "deer"). Reference to car horns is first recorded 1901. Figurative senses of Latin cornu included "salient point, chief argument; wing, flank; power, courage, strength." Jazz slang sense of "trumpet" is by 1921. Meaning "telephone" is by 1945.

Trumpets were at first horns perforated at the tip, used for various purposes (Josh. 6:4,5). Flasks or vessels were made of horn (1 Sam. 16:1, 13; 1 Kings 1:39). But the word is used also metaphorically to denote the projecting corners of the altar of burnt offerings (Ex. 27:2) and of incense (30:2). The horns of the altar of burnt offerings were to be smeared with the blood of the slain bullock (29:12; Lev. 4:7-18). The criminal, when his crime was accidental, found an asylum by laying hold of the horns of the altar (1 Kings 1:50; 2:28). The word also denotes the peak or summit of a hill (Isa. 5:1, where the word "hill" is the rendering of the same Hebrew word). This word is used metaphorically also for strength (Deut. 33:17) and honour (Job 16:15; Lam. 2:3). Horns are emblems of power, dominion, glory, and fierceness, as they are the chief means of attack and defence with the animals endowed with them (Dan. 8:5, 9; 1 Sam. 2:1; 16:1, 13; 1 Kings 1:39; 22:11; Josh. 6:4, 5; Ps. 75:5, 10; 132:17; Luke 1:69, etc.). The expression "horn of salvation," applied to Christ, means a salvation of strength, or a strong Saviour (Luke 1:69). To have the horn "exalted" denotes prosperity and triumph (Ps. 89:17, 24). To "lift up" the horn is to act proudly (Zech. 1:21). Horns are also the symbol of royal dignity and power (Jer. 48:25; Zech. 1:18; Dan. 8:24).
