1.
substance, true form, true nature
The real or essential nature of something, as opposed to its surface appearance. Used when trying to uncover what something really is beneath its outward form.
Usage
Do not confuse with the homophone 実態 (actual conditions, real situation). 実体 focuses on the essential nature or substance of something, while 実態 focuses on the actual state of affairs or conditions. In philosophy, 実体 translates the concept of "substance" (as in Aristotelian substance).
