What is the meaning of "fetter" in a physical context?

In a physical context, "fetter" specifically refers to a restraint or shackle, typically used for the ankles. This term is often associated with the limitations imposed on movement, drawing from its historical use in contexts where individuals were confined or restricted by physical restraints. By understanding "fetter" in this way, one can appreciate its implications of both physical bondage and the broader metaphorical use in language to signify limitations or restrictions in various contexts. The other choices do not relate directly to the physical meaning of "fetter" and instead represent different concepts altogether, such as performance, leadership roles, or processes of division.
