Gammon is the 'ham' sense is from Old North French 'gambon' ('ham'), from 'gambe' ('leg'); the 'nonsense' sense is separate 19th-century slang, perhaps from 'backgammon' or 'gammon and patter'. The history is deliberately cautious: the proposed comparison is useful for orientation, but the wording leaves room for uncertainty rather than forcing a false certainty. In present use, it is used as a noun and verb meaning "cured ham from a pig's hind leg; nonsense or humbug", so the historical material remains connected with the current sense rather than standing as bare ancestry. The named historical forms include Old French gambon and Late Latin gamba, keeping the history tied to concrete forms rather than a loose resemblance. Its semantic neighborhood includes ham, bacon, nonsense, and humbug, locating the modern specialization without adding a new origin story.
