muffler

The term describes two entirely different objects that share the common function of dampening or insulating. In automotive contexts, it refers to the mechanical component that suppresses the loud explosions of an engine, creating a quieter ride.

In a textile context, it refers to a heavy scarf. While "scarf" is the more common modern term, "muffler" specifically evokes a sense of thickness and heavy-duty protection against extreme cold, often associated with traditional winter attire.
