Word History

Etymology

Verb

Middle English aken, going back to Old English acan, of uncertain origin

Note: Originally a Class VI strong verb, to judge by Middle English past tense forms such as eoc, ok, etc. (no preterit forms are attested in Old English). There is no counterpart to the verb in other Germanic languages, and words adduced as possible relatives (e.g., Middle Dutch akel "harm, injury, grief," Middle Low German ēken "to fester") are formally and semantically only vaguely comparable. Regarding the spelling see note at ache entry 2.

Noun

Middle English, going back to Old English æce, ece, noun derivative from the base of acan "to ache entry 1"

Note: The spelling with -ch-, reflecting the historical pronunciation of the noun, has spread to the verb, while the pronunciation of the verb with [k], continued from Old English, has spread to the noun since late Middle English. The persistence of the spelling with -ch- may have been influenced by Samuel Johnson's mistaken notion that the word derived from Greek áchos "pain, distress."
