The Spanish for “horn”, cuerno (and its variations, like the ever-present cornudo), and the English horn are both originally the same word in the ancient languages.
Huh?
One of the most interesting sound shifts is the Indo-European “k-” sound remained the same into Latin and then Spanish (the Latin cornu for the same) but became an almost-silent “h-” in the Germanic languages.
Thus the c-r-n in Spanish parallels exactly the h-r-n in English.
There are lots of awesome and subtle examples of this pattern, such as Corazon/Heart.
