In a cankered manner; in a way that shows corruption, disease, or decay.
Formed by adding the adverbial suffix '-ly' to the adjective 'cankered'. A regular English formation allowing the description of actions or states done in a diseased or corrupted way.
This adverb is rare in modern English, but it shows how Renaissance writers could pile on suffixes to create very specific meanings—'cankeredly' paints a picture of something spreading corruption as it moves.
