What does cankered mean?
"Cankered" is an adjective describing something eaten away or destroyed by canker — literally, a destructive fungal disease that blights trees and shrubs, or an ulcerous sore in humans and animals. More commonly today it is used figuratively: a person, heart, or mind described as cankered has become embittered, corrupt, or festering with resentment, envy, or malice, as though some hidden sore were slowly consuming it from within. The word carries strongly negative connotations and appears most often in literary, formal, or deliberately expressive writing — "a cankered heart," "cankered with jealousy." It derives ultimately from Latin "cancer" (crab, then spreading sore), which also gave English "cancer" and "chancellor." Because its literal sense survives mainly in gardening and veterinary contexts, readers encountering "cankered" in prose should usually understand it metaphorically: something wholesome that has been inwardly rotted by long-nursed bitterness.
Eaten into or damaged by canker; figuratively, corrupted or made bitter by festering resentment, envy, or malice.
"A cankered rosebush was pruned back hard in the hope of new growth."
The figurative sense dominates modern usage; the literal horticultural sense survives chiefly among gardeners.
Past participle of 'canker': to have infected, corrupted, or gnawed away at something.
"Jealousy had cankered their friendship until nothing remained but suspicion."
Shakespeare used 'canker' for both a plant-eating worm and an eating sore — so 'cankered' has always meant two kinds of rot at once: in gardens and in hearts.

Etymology of cankered
The verb "canker" entered Middle English from Old North French "cancere," from Latin "cancer," meaning crab and later a spreading ulcerous sore. "Cankered" arose as its past participle, first attested in late Middle English, and came to describe anything eaten away by such sores — including the plant disease gardeners still call canker. By extension it acquired its figurative moral sense of being corrupted or embittered. Its cognates include "cancer" and "chancre," all tracing back to the same Latin root.
