1785 (implied in malingerer), from Fr. malingrer "to suffer," perhaps also "pretend to be ill," from malingre "ailing, sickly," possibly a blend of mingre "sickly, miserable" and malade "ill." Mingre is itself a blend of maigre "meager" + haingre "sick, haggard," possibly from Gmc. (cf. M.H.G. hager "thin"). The sense evolution may be through notion of beggars with sham sores.
