Adjective. Archaic (chiefly northern). Mid-18th century.
[from BLACK adjective + French vis face (perhaps originally black-à-vis or black o'vis) + ED.]
Blackavised is an unusual word in juxtaposing naked English and French so overtly. While it's fallen out of popular usage, it can be found in a number of classics and, in a similar manner to the word 'swarthy' which is used by several dictionaries in defining blackavised, it can describe someone's simmering, sun-kissed complexion, the rugged handsomeness and rough beauty of a person that is rarely indoors.
