Looking for the meaning or definition of the word -k-? Here's what it means.
Interfix
(chiefly in verb forms) Added after a word’s terminal ‘c’ when it is suffixed by a morpheme beginning in ‘e’, ‘i’, ‘y’, ‘æ’, or ‘œ’ (usually -ed or -ing), so as to preserve its “hard” [k] sound (as opposed to [s]).
