Etymology

*/kamukapu/ → /kamuɡapu/ → /kanɡafu/ → /kanɡaferu/ (regular change for lower bigrade verbs) → */kangaweru/ (semi-regular sound shift for the /f/ phoneme: ハ行転呼 (ha-gyō tenko)) → /kanɡajeru/ (semi-regular sound shift, collapsing /we/ into /je/) → /kanɡaeru/

From Old Japanese. First cited to the Nihon Shoki of 720.[1]

Ultimate derivation uncertain. Theories include:

  • Given the ancient kamugapu spelling, may be ka + mukau, where the ka is an unidentified prefixing element, or possibly 処 (ka), cognate with the こ (ko) in location determiners like ここ (koko, “here”), どこ (doko, “where”), and the mukau is 向かう (mukau, “to face something, to face a direction”, pronounced as mukapu in ancient times), from the sense of facing a thing or issue to thoroughly inspect it and think it over.[2] The shift from mukapu to mugapu may be an example of assimilation and lenition, where the preceding /m/ softens the following /k/.
  • Alternatively, may be derived from the on'yomi of kan for the character 勘 (kan, “intuition, perception”, prior to the development of the kana ん, this would have been spelled as kamu),[2] plus some unknown element that was probably originally kapu, changing to gapu due to rendaku. The semantically relevant verbs with ancient readings of kapu, such as 変える (kaeru, “to change”) all have to do with ideas of changing or turning, suggesting a possible original meaning of to change one's perception. In addition, there are also obsolete readings of かうがふ (kaugafu) and かがふ (kagafu), giving further support for this etymology.
