dishonest
adj.
late 14c., from Old French deshoneste (13c., Modern French déshonnête) "dishonorable, horrible, indecent," perhaps from a Medieval Latin or Gallo-Roman compound of Latin dis- "not" (see dis-) + honestus "honorable" (see honest). The Latin formation was dehonestus. Related: Dishonestly.
