Is Sound Board a Metaphor or an Idiom?
While sounding board can be seen as metaphorical—a board that reflects or magnifies sound—in this context, it’s considered an idiom. Idioms are fixed expressions where the meaning isn’t directly clear from the individual words. So, when you tell someone they’re your sounding board, you aren’t asking them to literally amplify sound with a thin piece of wood. You just want them to lend an ear and give feedback.
The Meaning of the Idiom Sounding Board
The idiom sounding board simply means someone who actively listens to your thoughts, allowing you to bounce ideas off them and gain clarity. It’s about having that go-to person who offers feedback. For some, it’s their mothers. For others, it’s a best friend.
Origin and Etymology of the Idiom Sounding Board
The term “sounding board” originally referred to a structure placed above and behind a pulpit or stage to help reflect sound waves toward the audience, amplifying the speaker’s voice. Eventually, this tangible concept evolved into the figurative expression we use today. By the late 18th to early 19th centuries, it was adopted as an idiomatic way to describe someone offering reflective feedback on ideas or thoughts.
