實體

维基百科，自由的百科全书

實體(entity)是有可區別性且獨立存在的某種事物，但它不需要是物質上的存在。尤其是抽象和法律擬制也通常被視為實體。In general, there is also no presumption that an entity is animate. Entities are used in system developments as models that display communications and internal processing of say documents compared to order processing

實體可被看成是一包含有子集的集合。在哲學裡，這種集合被稱為客體。

實體可被使用來指涉某個可能是人、動物、植物或真菌等不會思考的生命、無生命物體或信念等的事物。在這一方面，實體可以被視為一全包的詞語。

有時，實體被當做本質的廣義，不論即指的是否為物質上的存在，如時常會指涉到的無物質形式的實體－語言。更有甚者，實體有時亦指存在或本質本身。

在法律上，實體是指能具有權利和義務的事物。這通常是指法人，但也包括自然人。
