OriginLate Middle English (denoting a median vein or nerve): from medieval Latin medianus, from medius 'mid'. mean from Old English: The word mean means many things in English. The ancient root of Old English mean ‘to intend to convey’ is related to mind. The original meaning of mean ‘not generous, small-minded’ (Middle English) was ‘common to two or more people’, reflecting its ancient root, shared with Latin communis ‘common’ (see commonplace). Modern uses developed from ‘low on the social scale’ through ‘inferior’, while a complete reversal comes in the informal sense ‘excellent’, dating from the early 20th century. Use as a term of approval has a precursor in expressions involving a negative, no mean…: in the Bible St Paul declared ‘I am …a Jew of Tarsus…a citizen of no mean city.’ The mathematical use of mean, ‘an average’ (Middle English), goes back to Latin medianus ‘middle’, source also of median (Late Middle English). This is the mean behind means ‘a method’, as in a means to an end, a thing that is not valued or important in itself but is useful in achieving an aim.
