na-adjective
Describes a quality or property that exists inherently within something, rather than being imposed from outside. Often used in philosophical, academic, or formal contexts.

芸術の内在
We discuss the immanent value of art.
固有 means 'inherent' or 'characteristic' and is often used for properties unique to something, whereas 内在的 is more about internal existence.
Compound of 内在 (ないざい, 'immanence, being within') + 的 (てき, '-like, -ic'). The base 内在 is from 内 (ない, 'inside') + 在 (ざい, 'exist').
