Etymology Origin:
The word immobile traces back to Latin immobilis, combining the negative prefix im- (variant of in-) with mobilis (movable). The root movere (to move) is foundational in English, appearing in words like motion and mobile. Over time, immobile retained its literal sense of "unmovable" while also acquiring figurative meanings like "unchanging."
