complain

complain: [14] Complain goes back to the Latin in verb plangere, source also of English plangent. This was formed on a prehistoric base *plak- (from which we also get plankton), and it originally meant ‘hit’. Its meaning developed metaphorically through ‘beat one’s breast’ to ‘lament’, and in medieval Latin it was combined with the intensive prefix com- to produce complangere. When it entered English via Old French complaindre it still meant ‘lament’, and although this sense had died out by about 1700, traces of it remain in ‘complain of’ a particular illness. Complaint [14] came from Old French complainte.
=> plangent, plankton

Older sense of "lament" died out 17c. Related: Complained; complaining.
