late 14c., "causing discomfort, dismal;" c. 1400, "unhappy, dejected, melancholy, wanting consolation or comfort," from Medieval Latin disconsolatus "comfortless," from Latin dis- "away" (see dis-) + consolatus, past participle of consolari "offer solace, encourage, comfort, cheer," from assimilated form of com-, here probably an intensive prefix (see com-), + solari "to comfort" (see solace).
