Etymology and origin of the English word addle

History Permalink

Pronunciation

  • IPA: /ˈæd.əl/[1]

Etymology

It comes from Middle English adel “rotten”,[2][3][4][5][6] from Old English adela “mud, mire, liquid filth”,[2][3][4][5][6] related to Middle Low German adele “liquid manure”[5][6][4] and Old Swedish adel “urine”.[3][4] It is of unknown origin.[3]

Earliest recorded meaning

In adel eye “rotten egg” (about 1250),[3][4][7] a translation of Medieval Latin ovum urinae “egg of urine”,[3][7] itself a misrendering of Latin ovum urinum, Greek oúrion ōón “wind egg”,[3][4] an egg that does not hatch.[4][3]

Semantic evolution

Because the noun was used before egg, it came to be taken as an adjective meaning “rotten” (1592),[7][4] and by analogy with a rotten egg “empty, muddled, confused”.[3][4][7] Compounds such as addle-pate (about 1600) and addle-headed (1660s) followed.[4][3] The verb, to muddle or confuse, is recorded from 1646 as addled in Barnhart and Etymonline.[3][4]
