strut

An strut is a supportive or decorative piece that holds something up.

When you think about it, we use "strut" a lot in everyday language. For example, if a model walks down the catwalk with her shoulders back and head held high, people might say she's showing off her best strut. It's like she's proudly strutting around to show everyone what she's got. We also talk about struts on cars - those metal bars that support the wheels, making sure they stay up even when you're driving over bumps or potholes.
