Not having an independent nature, not a nature of its own, but constituted of elements.

A Dictionary of Chinese Buddhist Terms, William Edward Soothill and Lewis Hodous

依他起性 [py] yītā qĭxìng [wg] i-t'a-ch'i-hsing [ko] 의타기석 ŭit'agisŏng [ja] エタキショウ etakishō ||| (paratantra-svabhāva) (1) The nature of existence as arising from dependence on other things; said of existence arising from causes and conditions. Also expressed as 縁有.(2) That which is born of causes and conditions and will cease when causes are absent. In Consciousness-only theory, it refers to the 94 conditioned elements. Though existing, it does not exist in a fundamental sense, yet it cannot be called non- existent (無). This is called a "provisional existence" (jiayoufa 假有法) or "not existing, appearing to exist" (feiyousiyou 非有似有).
