bolster
UK: ˈbəʊlstə | US: ˈboʊlstər
n. a long, firm pillow or cushion
vt. to support, strengthen, or reinforce
The word "bolster" originates from Old English bolster, derived from Proto-Germanic bulstraz, meaning "pillow" or "cushion." The root bol- relates to a beam or trunk, suggesting the idea of firm support. Over time, it evolved to denote both the physical object (a long pillow) and the action of providing support (verb form). The suffix -ster historically indicated an agent or tool, reinforcing the functional aspect of the word.
