Berry
Berry, strictly speaking, a succulent, inferior, syncarpous fruit, neither horny exteriorly as in gourds, nor having a core as in the pome of the apple, hawthorn, or service-trees. A gooseberry, banana, or prickly pear are true berries; but the term is often more loosely used, either for similar superior fruits, such as the tomato or grape, or even for apocarpous drupes; for etaerios of drupels, such as the raspberry; or for other fruits of quite different structure, such as the strawberry; or even for the united fruit-structures of several flowers, as in the mulberry.
