Etymology

It is inherited from Middle English normal,[2][3] borrowed from Late Latin normālis (“in conformity with rule, normal”),[4][3] in classical Latin “made according to a carpenter's square”,[4][2][3] from Latin norma (“carpenter's square; rule, pattern”),[4][2] a word of unknown origin according to Etymonline,[4] while Merriam-Webster derives it, probably, from Greek gnōmona, the accusative of gnṓmōn “pointer on a sundial, carpenter's square”.[5] It is related to norm.[3][4]

Earliest recorded meaning

“Typical, common”, of a verb, in grammar: before 1500, in the Middle English translation of Donatus,[3] or about 1500.[4]

Semantic evolution

In geometry normal meant “at a right angle, perpendicular” from 1650[6] or the 1640s,[4] and a perpendicular from 1727.[4] The general meaning “conforming to the usual type, regular” is attested from 1828, but Barnhart thinks it must have been used earlier.[3][4][6] As a noun, “the usual state”, it is from 1890.[4] A normal school, a training college for teachers, from 1835, translates French école normale (1794), meant to set a standard.[4] “Heterosexual” is by 1914.[4] Normalcy meant being at right angles in 1857, and was popularized in its general sense by President Warren G. Harding in 1920.[3]
