late 14c., from Old French indigence "indigence, need, privation" (13c.), from Latin indigentia "need, want; insatiable desire," from indigentem (nominative indigens), present participle of indigere "to need," from indu "in, within" + egere "be in need, want," from PIE *eg- "to lack" (cognates: Old Norse ekla "want, lack," Old High German eccherode "thin, weak").
