"Leaguer"
In its literal sense, the term "leaguer" refers to a military encampment; Shakespeare uses the word in this original sense in All's Well That Ends Well, Act III, scene 6, line 26: "the leaguer of the adversaries." By the 1630s the word had become a slang term for a whorehouse, as here in this play, or in the 1640 play The Knave in Grain.
