Pronunciation

Etymology

It is inherited from Middle English errour,[2][3] borrowed from Old French error (“mistake, flaw, defect, heresy”), errour,[4][2] from Latin error (“a wandering, straying; doubt; mistake”),[4][2] from errāre “to wander, err”,[4][2][5] the source of err.[4][2] The usual spelling until the end of the 18th century was errour, as in Johnson's Dictionary.[2][4]

Earliest recorded meaning

The condition of erring, holding mistaken opinions: before 1300 in the OED, probably before 1300 in Barnhart, in Arthour and Merlin.[6][2] A mistake, and an offence against morality: about 1300 in Etymonline,[4] about 1303 in Barnhart, in Mannyng's Handlyng Synne.[2]

Semantic evolution

False belief or heresy is from the early 14th century,[4] and deviation from what is normal, an aberration, from the late 14th century.[4] A flaw in the making of a thing is from 1398,[6] and in law a mistake in the proceedings of a court from 1495.[6] The literal sense, roaming or wandering, appears in English from 1594, after Latin.[6] In science, the difference between an observed and a true value is from 1726.[4] Words for error in most Indo-European languages originally meant “to wander, go astray”, while Irish dearmad is from “a forgetting”.[4]
