horn: [OE] Horn belongs to a very large Indo- European word-family that has made an enormous number of contributions to English. Its ultimate source is Indo-European *ker-, whose offspring predominantly denote ‘animal’s horn’, but also include words for ‘top’ and ‘head’. Its Germanic descendant, *khornaz, has not been that prolific (it has produced English, German, Swedish, and Danish horn and Dutch hoorn, and hornet is probably a derivative), but other branches of the family have been more fruitful sources.

From Latin cornū ‘horn’, for example, come English corn ‘hard skin’, cornea, corner, cornet, cornucopia, unicorn, and possibly scherzo and scorn; Greek kéras ‘horn’ has given English keratin, rhinoceros, and triceratops; while Sanskrit śrngam ‘horn’ lies behind English ginger.

And besides these, English hart ‘male deer’ [OE] goes back to a derivative of *ker-.
