Pepper n. 1.A well-known, pungently aromatic condiment, the dried berry, either whole or powdered, of the Piper nigrum. Note: Common pepper, or black pepper, is made from the whole berry, dried just before maturity; white pepper is made from the ripe berry after the outer skin has been removed by maceration and friction. It has less of the peculiar properties of the plant than the black pepper. Pepper is used in medicine as a carminative stimulant.
2.(Bot.) The plant which yields pepper, an East Indian woody climber (Piper nigrum), with ovate leaves and apetalous flowers in spikes opposite the leaves. The berries are red when ripe. Also, by extension, any one of the several hundred species of the genus Piper, widely dispersed throughout the tropical and subtropical regions of the earth.
3.Any plant of the genus Capsicum (of the Solanaceae family, which are unrelated to Piper), and its fruit; red pepper; chili pepper; as, the bell pepper and the jalapeno pepper (both Capsicum annuum) and the habanero pepper (Capsicum chinense); . These contain varying levels of the substance capsaicin (C18H27O3N), which gives the peppers their hot taste. The habanero is about 25-50 times hotter than the jalapeno according to a scale developed by Wilbur Scoville in 1912. Note: The term pepper has been extended to various other fruits and plants, more or less closely resembling the true pepper, esp. to the common varieties of Capsicum.
