pullulate

pullulate: [17] The etymological notion underlying pullulate is of rapid ‘new growth’. It goes back ultimately to Latin pullus ‘young animal’, which also produced English pony and poultry and is distantly related to foal. From this was derived the verb pullulāre ‘grow, sprout’, whose past participle provided English with pullulate. This too originally meant ‘sprout’, a sense largely displaced since the 19th century by its metaphorical descendant ‘swarm, teem’.
=> foal, pony, poultry, pullet
