pin (noun, verb) /pɪn/ LISTEN
A pin is a small piece of metal used as a fastener or support, as well as many different forms of fasteners, badges, or ornaments made with sharp wires. It is also a short metal, wooden, or plastic rod driven through holes in adjacent parts of something, like the hub of a wheel and its axle, in order to hold those parts together. Informally, legs can be called pins, although this is now rather dated. As a verb, to pin means ‘to fasten with or as with a pin’ and ‘to hold something or someone still in one place.’ Unrelatedly, a PIN is also an identification number that gives you access to an automatic machine or other device.

Pin dates back to before the year 1100. The late Old English pinn and the Middle English pinne meant ‘peg or bolt,’ It can be traced back to the Proto-Germanic root penn– (juttinng point or peak) and the Latin pinna or penna, which could mean ‘a pinnacle,’ ‘a promontory or cape,’ ‘a battlement’ and ‘a point’ (of different types), as well as ‘a feather or plume,’ ‘a wing’ (in the plural), and ‘a fin.’ There is some debate about whether pinna and penna were two variations of the same word with many meanings, derived from the Proto-Indo-European root pet– (to rush or fly), which would make pin related to the English word pen, or pinna and penna were separate, with penna holding the meanings related to feathers, fins and wings, and pinna the meanings related to points and peaks. In this version, pinna is derived from the Proto-Indo-European spei– (sharp point), and is related to the English spike. Either way, pin is definitely related to the Old Saxon pin (peg), the Old Norse pinni (peg or tack), the Middle Dutch pin (pin or peg), the Old High German pfinn and the German Pinne (pin or tack). The modern, thin wire pin dates back to the 14th century, while the figurative use for legs is from the early 16th century. The expression “pins and needles” dates back to the early 19th century. The verb comes from the noun and, meaning ‘to affix with a pin,’ dates back to the mid-14th century. The meaning ‘to hold someone down’ is from the early 19th century.
