Etymology

The word tremulous traces back to Latin tremulus (trembling), from tremere (to shake). The suffix -ulous amplifies the root, creating an adjective meaning "full of trembling." Over time, it evolved to describe both physical quivering (e.g., leaves) and emotional nervousness, reflecting the dual nature of involuntary movement and fear.
