Etymology
the adjective "motionless" is a transparent compound formed within english from the native noun "motion" and the productive suffix "-less." the noun "motion" itself has a deep lineage, originating from the latin verb movēre, "to move," which traces back to the proto-indo-european root mew-, "to push away." the suffix "-less" is of germanic origin, a staple in english for forming adjectives that denote an absence. the literal construction "without motion" perfectly captures the modern abstract meaning of complete stillness, demonstrating how english readily combines latinate and germanic elements to create precise descriptive terms.
Analysis
motion: from latin mōtiōnem (nominative mōtiō) "a moving, a motion," from past participle stem of movēre "to move." functions as the core noun root. less: from old english -lēas "free from, without," from proto-germanic -lausaz. functions as an adjective-forming suffix meaning "lacking, devoid of."
