I want to be given more explanation on this. It’s common belief that Sigmund Frued coined the term “uncanny” after reading E.T.A. Hoffman’s work, “Der Sandman”. Is this true?

uncanny
1596, “mischievous;” 1773 in the sense of “associated with the supernatural,” originally Scottish and northern English, from un- (1) “not” + canny.

canny
1637, Scottish and northern England formation from can in its sense of “know how to.” Often used superciliously of Scots by their southern neighbors, implying “thrift and an eye to the main chance.”
