To sprout is to send up a first small shoot. Seeds sprouting, sprout leaves, sprouted in a week.
It is what a seed does when warmth and water reach it, and sprouting is also a deliberate kitchen process — beans and seeds are sprouted for eating. Figuratively anything can sprout: sprouting a beard, new shops sprouting everywhere. As a noun, sprouts are Brussels sprouts in Britain by default, and no other vegetable divides a Christmas table so reliably.
