burgeon - v.i., to put forth new buds or greenery, sprout; to grow or develop rapidly.
Used since at least the late 13th century as burjonen or burjon, from Anglo-French burjuner, from burjun, bud, from Old French burjon from a conjectured Vulgar Latin form *burriōn(em), accusative of *burriō, from Late Latin burra fluff, apparently from the down covering some buds (like willow catkins?). Pronounced BUR-juhn.
