undue

Etymology

It is formed from English un- + due,^{[2][3][4][5][6]} first as inherited from Middle English undewe,^[6][7] on the model of Old French indeu and Latin indēbitus.^[2][3] The Shorter Oxford names indu as the model.^[4] The base adjective comes from Old French deu, past participle of devoir (“to owe”), from Latin dēbeō (“to owe”).^[3]

Earliest recorded meaning

Not properly owing or payable, as a debt: 1387, in John Trevisa's translation of Higden's Polychronicon;^[2] Etymonline dates it to the late 14th century.^[3]

Semantic evolution

From "not owed", the word passed in the late 14th century to "not appropriate, unseasonable" (1398, also in Trevisa) and to "unjustly demanded".^[2][3] By the early 15th century it also meant contrary to what is just or lawful.^[2][6] The modern main sense, "going beyond what is fitting; excessive", is dated by the OED only from before 1684,^[2] and Hoad places it in the 17th century,^[5] while Etymonline and the Shorter Oxford find it already in late Middle English.^[3][4] The original sense "not yet payable" survives, though rarely.^[4][8][6] Johnson (1755) gave "not right; not legal" and "not agreeable to duty".^[9] In law, undue influence is pressure under which a person enters into a transaction without independent judgement.^[4]

Usage notes

Collins advises against phrases such as there is no cause for undue alarm, where the word is redundant.^[8] Etymonline quotes Fowler's Dictionary of Modern English Usage (1926) making the same point about there is no need for undue alarm.^[3]
