What does bolster mean?
A bolster is a long, firm cushion traditionally placed on a bed to support the head, arms, or back, though it also refers more generally to any padded support on a seat or sofa. Far better known today is its verb form: to bolster means to support, strengthen, or reinforce something — a person's confidence, an argument, a company's profits, or a nation's economy. The word carries a constructive, stabilizing connotation; to bolster something is to make it firmer and more resilient rather than merely to help it temporarily. Journalists frequently use it in phrases like 'bolster morale' or 'bolstered by strong earnings', making it a staple of political and business writing. Etymologically, both senses share one origin: Old English 'bolster', a cushion whose name may derive from a Germanic root meaning 'swollen', fittingly describing a plump, stuffed pillow. That literal cushion became a metaphor for anything that props up or reinforces, giving English a single compact word that spans bedroom furnishings and macroeconomic policy alike.

Etymology of bolster
Bolster comes from Old English 'bolster', meaning a long bed-cushion, which traces back to a Proto-Germanic root related to swelling or bulging — apt for a stuffed, rounded pillow. It has close cognates in other Germanic languages, notably German 'Polster' (a cushion). The verb sense, meaning to prop up or reinforce, developed from the literal image of padding or supporting with cushions, and was well established by the sixteenth century.
How bolster is actually used
The verb is common in formal and journalistic registers, especially in political and economic reporting, where it often appears in phrases like 'bolster the economy' or 'bolster confidence'. The noun sense is more domestic and everyday. The verb carries a neutral-to-positive connotation, implying helpful reinforcement rather than mere temporary relief.
