Etymology

Origin of nail

First recorded before 900; Middle English (noun) nail, nayl, Old English nægl, cognate with Old Frisian neil, Old Saxon, Old High German nagal, Dutch nagel, German Nagel, Old Norse nagl “fingernail,” all from unattested Germanic naglaz; akin as derivative to Lithuanian nãgas, nagà “hoof,” Old Prussian nage “foot,” Old Church Slavonic noga “leg, foot” ( Serbo-Croatian nòga, Czech noha, Polish noga, Russian nogá; probably originally a jocular reference to the foot as a hoof), Old Church Slavonic nogŭtĭ, Tocharian A maku, Tocharian B mekwa “fingernail, claw,” all from unattested North European Indo-European ənogwh-; further akin to Old Irish ingen, Welsh ewin, Breton ivin, from unattested Celtic ṇgwhīnā, Latin unguis, from unattested Italo-Celtic əngwhi-; Greek ónyx, stem onych-, Sanskrit áṅghri- “foot” from unattested áṅghli-; Armenian ełungn, from unattested onogwh-; Middle English (verb) nail(e), nayle, Old English næglian, cognate with Old Saxon neglian, Old High German negilen, Old Norse negla, from unattested Germanic nagl-janan; compare Gothic ganagljan

Explanation

A nail is the pointed piece of metal that you pound with a hammer when you're building something. When you go to a nail salon, however, don't bring a pack of nails; bring your toes and fingers instead! When construction workers pound nails into wood, they nail them. Another kind of nail is the one at the end of each of your fingers and toes. In addition to hitting a nail, the verb version of nail also means "to arrest," "to succeed easily," and "to hit." Nail polish is what you use to color the nails on your hands (or feet), and when you "hit the nail on the head," you get the exact right answer.
