unbeknownst

/ənbiˈnoʊnst/ adj B1

not known

Word Origin A wonderfully archaic word: un- 'not' + be- 'thoroughly' + known + -st (an old superlative ending). So unbeknownst literally means 'not thoroughly known' — something that's completely unknown. It's a cousin to unknown, knowledge, and acknowledge, all from the Old English root cnāwan 'to know.'
