Etymology
The word 'normal' originates from the Latin 'normalis', meaning 'made according to a carpenter's square', which itself derives from 'norma', a tool for establishing right angles and, by extension, a standard or rule. This concrete, geometric sense evolved metaphorically to signify conformity to a pre-established standard or pattern. The journey from a physical tool for ensuring perpendicularity to an abstract concept describing statistical averages or societal expectations illustrates a classic path of semantic broadening, where a specific technical term gains generalized figurative meaning.
