To bolster something is to support or strengthen it, especially an idea, feeling, or system.
It originally referred to a long pillow or cushion, from Old English “bolster,” meaning “pillow” or “support.” The verb sense grew from the idea of physically propping something up.
A bolster pillow literally props you up, and the verb does the same thing for confidence, arguments, or economies. The word quietly reminds us that strength often comes from hidden supports behind the scenes.
