As a verb, swallow means "to enclose or envelop completely," like quicksand that swallows everything that falls into it. Swallow can also mean "to stop from expressing," like when you swallow your pride and ask for help. The noun swallow describes a gulp, though you don't always do it for digestion; sometimes a few swallows of air help you keep from crying. A swallow is also a type of small songbird.
