柅

• Mechanical: A brake, wedge, or stop-block used to arrest the motion of a carriage or secure a heavy object against rolling.
• Botanical: A species of hardwood tree.

Primarily functions as a noun. If encountered in a verbal position, it likely means "to stop," "to brace," or "to fix in place."

The gloss "flourish" appears in some reference materials but is not well-attested in standard classical usage and may be a ghost-meaning. It should only be considered if the context is explicitly botanical and no other reading fits.
