Word of the day

Gaslight  – a  lamp in which an incandescent mantle is heated by a jet of burning gas;  light made by burning illuminating gas; to manipulate someone by psychological means into doubting their own sanity; to use an elaborate and insidious technique of deception and psychological manipulation to gradually undermine the victim’s confidence in her/his own ability to distinguish truth from falsehood, right from wrong, or reality from appearance, thereby rendering her/him pathologically dependent on the gaslighter in her/his thinking or feelings.
