What does knag mean?
Knag means to nag, particularly to complain repeatedly or to keep asking someone to do something in a persistent and irritating way. Its modern sense belongs chiefly to northern British English and nearby regional varieties, where it remains a familiar alternative to the more widely used verb “nag.” For example, someone might “knag about” a broken appliance or “knag a neighbour” to repair a shared fence. The term can sound informal or old-fashioned outside those regions, so “nag” is usually the appropriate choice in neutral standard English. It should not be confused with “snag,” which denotes an obstacle, defect, or snag in fabric rather than persistent complaining. Although the spelling differs, the two words are pronounced similarly, and both convey the idea of something troublesome obstructing progress.

"Her parents kept knagging her to come home earlier."

Knag preserves the older, northern English sound of the word that survives in standard English as nag.

Where does knag come from?
Knag is of Scandinavian origin, probably connected with an Old Norse word meaning a knot or snag in wood. The word entered Middle English in forms associated with both a projecting knot in timber and persistent complaining. Modern usage is concentrated in northern British dialects, while the more familiar “nag” became the standard form in wider English.
