"This is much used in some parts of New England instead of well or very well. In answer to the common salutation, How do you do? we often hear, I am cleverly. It is also applied to other things, as well as to health, and means either adroitly or exactly; according to the case."--Pickering. It is also used in the sense of fairly, completely. Dr. Johnson's definition is dextrously, fitly, handsomely.
The landlord comes to me, as soon as I was cleverly up this morning, looking full of importance.--Sam Slick in England, ch. 8.
