This looks like a line from Shakespeare's King Lear , specifically about the phrase "swearing about a wagon broken in four." It refers to someone cursing or complaining excessively about something that is broken or ruined. If you're looking for a clearer explanation or context, here it is:

• "Swearing about a wagon broken in four" means angrily complaining about a situation or an object that has fallen into multiple broken pieces — a metaphor for a severely damaged or ruined state.
