Consider the following meanings for the English word butt:
the target of a joke (He was always the butt of any practical joke in the office);
a cigarette end (Please donít throw your butts in the gutter);
a large cask for wine (Falstaff could drink a butt of wine at a single sitting);
an archery target (The arrow hit the exact centre of the butt)
the blunt end of a rifle (The soldier hit me in the back with the butt of his rifle)
How would you arrange these in terms of homonymy / polysemy? (One polysemous word with four related meanings? Four separate homonyms? Two homonyms, each with sets of related meanings? etc.) Give supporting argument for your decision.
