Etymology
The word 'horn' descends directly from the Old English 'horn', which shares a common Proto-Germanic ancestor 'hurną'. This Germanic root can be traced further back to the Proto-Indo-European (PIE) root 'ḱer-', meaning 'horn' or 'head'. This ancient root is remarkably prolific, giving rise to words for horned animals and head-related concepts across many Indo-European languages, such as Latin 'cornū' (horn) and Greek 'keras' (horn). The semantic journey from the literal animal appendage to the modern meanings is a clear case of functional analogy: the material (animal horn) was used to make early musical instruments and drinking vessels, while the shape and function inspired the name for warning devices that project sound.
Analysis
The word 'horn' is a simplex word of Germanic origin. It functions as a single, unanalyzable morpheme in modern English.
Examples
The bull lowered its head, showing its sharp horns.
The driver pressed the horn repeatedly in the traffic jam.
