Etymology
The word 'bit' originates from the Old English verb 'bītan', meaning 'to bite'. The noun form evolved from the past participle 'bitten', referring to the action or result of biting, hence a piece bitten off. This concrete sense of a small fragment naturally extended to various abstract and technical meanings, including a short time (a 'bite' of time), the metal mouthpiece on which a horse 'bites', and, in the 20th century, the fundamental, indivisible 'piece' of information in computing. Its journey from a physical action to a unit of data exemplifies semantic broadening rooted in a core Germanic concept.
Analysis
The word 'bit' is a simplex word of Germanic origin. It functions as a noun in modern English.
