the adverb 'steadily' is built upon the old english noun stede, meaning a place or position, which itself traces back to the proto-germanic stadiz, related to the idea of standing firm. this root is part of a widespread indo-european family centered on the notion of standing, seen in latin stare (to stand) and greek histanai (to cause to stand). the core semantic shift moved from a physical 'place' to the abstract quality of 'stability' or 'firmness'. the addition of the adverbial suffix '-ly' transforms the adjective 'steady' into a modifier describing the manner of an action, thus 'steadily' literally means 'in a stable manner', evolving to describe actions performed with consistency, regularity, and without wavering.
