geezer: [19] Originally, a geezer seems to have been ‘someone who went around in disguise’. The word probably represents a dialectal pronunciation of the now obsolete guiser ‘someone wearing a masquerade as part of a performance, mummer’. This was a derivative of guise [13], which, together with disguise [14], goes back ultimately to prehistoric Germanic *wīsōn, ancestor of archaic English wise ‘manner’.
