Pronunciation: [nˈe͡ɪl fˈa͡ɪl] (IPA)

The "l" in both "nail" and "file" is pronounced distinctly, with a slightly different sound for each. Using a nail file regularly helps maintain healthy, neat-looking nails.
A nail file is a small handheld tool used for shaping and smoothing the edges and surface of fingernails and toenails. It is typically made of a slender, elongated piece of metal or cardboard with a rough or abrasive surface. The purpose of a nail file is to gently file down the length and sides of the nails, ultimately ensuring a desired shape and eliminating any rough edges or jagged, uneven surfaces.
Nail files come in various shapes, sizes, and materials, such as metal, glass, or even emery boards with embedded abrasive particles. Each type offers different levels of coarseness, allowing individuals to choose based on their specific nail needs and preferences. Some nail files feature a dual-sided design with different grits, offering versatility for various nail care tasks.
Using a nail file involves grasping the tool securely and positioning it at the desired angle against the edge or surface of the nail. Gentle, controlled pressure is then applied while moving the file in one direction, avoiding back-and-forth motions that create friction and potential nail damage. By using a nail file correctly, one can achieve a smoother, neat nail appearance and prevent nails from snagging or breaking.
Nail files are commonly found in grooming kits, salons, and households around the world, as they provide an essential tool for maintaining well-manicured nails and promoting overall nail health.
The word "nail file" consists of two parts: "nail" and "file".
The term "nail" can be traced back to the Old English word "naegel", meaning "fingernail" or "toenail". It has its roots in the Proto-Germanic word "naglaz" and the Proto-Indo-European word "onoghos". Over time, the meaning extended to refer to the thin, horny plate covering the dorsal surface of the fingers and toes.
The word "file" has its origins in the Latin word "filum", which means "thread" or "string". It then evolved into the Old English word "fīl", referring to a wire thread or thin strip of metal used for various purposes, including smoothing or shaping objects.
