false: [OE] False appears originally to have been borrowed directly from Latin falsus at the end of the 10th century, but without making much of an impression. It was only in the 12th century that it began being used with any frequency, probably as the result of an extra impetus given by reborrowing it via Old French fals. The word’s ultimate source was the Latin verb fallere ‘deceive’, from which English also gets fail, fallacy, fallible, and fault. => fail, fallacy, fallible, fault
