Nikāya (निकाय) is a Pāli word meaning "volume". It is often used like the Sanskrit word āgama (आगम) to mean "collection", "assemblage", "class" or "group" in both Pāḷi and Sanskrit.[1] It is most commonly used in reference to the Pali Buddhist texts of the Tripitaka namely those found in the Sutta Piṭaka. It is also used to refer to monastic lineages, where it is sometimes translated as a 'monastic fraternity'.
The term Nikāya Buddhism is sometimes used in contemporary scholarship to refer to the Buddhism of the early Buddhist schools.
尼柯耶(巴利語與梵語:Nikāya,尼迦耶),原義是收集、集合、分類、群體等[1]。在上座部佛教中,用來稱巴利藏中的經藏部份,相當於漢傳佛教中的阿含經(āgama)。在部派佛教中,上座部佛教所屬的派別,也被稱為尼柯耶派,相當於分別說部中的赤銅鍱部。也可以翻譯爲部,義爲部派。
