Etymology
The word 'fingernail' is a transparent compound from Old English, formed from the nouns 'finger' and 'nægl'. The Germanic root of 'finger' is of uncertain deeper origin, while 'nail' derives from the Proto-Germanic naglaz, tracing back to the Proto-Indo-European root h₃nogʰ- meaning "nail." This same root is the source for the nail (both anatomical and metallic) in many Indo-European languages. The compound's logic is perfectly literal, directly naming the hard, protective plate on the tip of the finger. Its meaning has remained stable and concrete from its Old English formation to modern usage.
