The word "nail up" does not have a specific etymology on its own as it is a phrasal verb formed by combining "nail" and "up". However, we can explore the origins of the word "nail" to understand its history.
The word "nail" can be traced back to Old English, where it was spelled "nægl" and had a similar pronunciation. It is cognate with other Germanic languages such as Old High German "nagal" and Old Norse "nagli". These words ultimately derive from the Proto-Germanic root "*naglaz".
The Proto-Germanic term "*naglaz" referred to both the fingernail/toenail and the metal nail. It is believed to have originated from the Proto-Indo-European root "*ongw-*", which means "to be attached" or "to grip tightly".
