What has a tongue but cannot taste?

This common riddle cleverly plays on the multiple meanings of words in the English language. When we think of a tongue, our minds often go straight to the muscular organ in our mouths that helps us speak, swallow, and, of course, taste. However, many everyday objects also possess parts that are named after human or animal body parts due to their shape or function.

A shoe, for instance, has a "tongue," which is the strip of material located underneath the laces or fasteners, resting on the top of your foot. Its primary purpose is to provide a layer of cushioning and protection between your foot and the lacing system, preventing the laces from digging into your skin and distributing pressure evenly across the top of your foot. It also helps to keep dirt and debris from entering the shoe, ensuring a more comfortable and secure fit throughout the day.

The use of the word "tongue" for this part of footwear highlights how we often borrow descriptive terms from the natural world to name components of manufactured items. Much like the "mouth" of a river or the "eye" of a needle, the shoe's tongue is a familiar example of anthropomorphism in language, allowing us to easily visualize and understand its placement and role, despite its complete inability to experience flavor.
