What does knavish mean?
Knavish is an adjective meaning dishonorable, deceitful, or unprincipled. It describes a person, character, action, or manner in which someone acts unfairly, manipulates others, or deliberately betrays trust. The word has a strongly moral and literary tone, suggesting more than ordinary bad behavior: a knavish person is not simply careless or impolite but is judged to be fundamentally dishonest or sly. It appears in phrases such as “a knavish trick” and “knavish behavior,” and it is especially associated with traditional English literature, where knaves and knavish schemes are familiar figures. Although the word can occur in British and American English, it sounds somewhat old-fashioned today and is more common in formal writing, historical texts, and deliberate, elevated prose than in casual conversation.

Etymology of knavish
Knavish was formed in the late 16th century from “knave,” a word for a dishonest or villainous man, together with the adjective-forming suffix “-ish.” “Knave” itself comes through Middle English from Old Norse “knapi,” originally meaning a servant or boy, and its sense developed toward “a bold or impudent fellow” and then “a dishonest or villainous person.” The related noun “knavery” developed from the same root and refers to knavish behavior or a dishonest act.
