Notes on Meaning

The primary modern meaning of doubly relates to degree or manner (e.g., doubly important). The archaic meaning related to deceit ("to deal doubly") is now rare and largely historical. In contemporary usage, the word almost always intensifies an adjective or verb by suggesting two reasons, aspects, or a multiplied degree.
