Etymology
Two Germanic etyma have been proposed, but it is not certain which one is correct, if either:
 * The first theory posits a borrowing from . The *w > *k is not entirely regular, but multiple explanations have been put forward (such as analogous gradation and a comparison with <  and  < ). LÄGLOS however considers derivation from  to be unlikely, although later support has been expressed by Schalin (2019).
 * Alternatively, according to Hyllested (2014), from earlier *ajeka and borrowed from (related to ); for medial *ajeC > *aiC, parallels exist in  (< *ajesa),  (< *kajekki) and probably  (< *ajetta). This etymology is supported by Junttila (2020).

Earlier proposals about a Baltic origin have been rejected.
