Etymology
The word "deep" originates from Old English dēop, meaning "extending far downward" or "profound." It shares roots with Proto-Germanic deupaz and is related to Old High German tiof and Old Norse djúpr. The core concept of depth—whether physical, emotional, or intellectual—has remained consistent across its evolution.
