The word 'eardrop' is formed from 'ear' (from Old English 'eare', meaning the organ of hearing) and 'drop' (from Old English 'dropa', meaning a small quantity of liquid). The word 'eardrop' refers to a liquid preparation designed to be placed in the ear.
Think of 'ear' as the organ for hearing and 'drop' as a small amount of liquid — that's why an eardrop is a liquid meant for the ear.
