Etymology

The word "depth" originates from Old English dēopþu, derived from dēop (meaning "deep") + the abstract noun suffix -þu (similar to modern "-th," as in "width" or "strength"). The root "deep" traces back to Proto-Germanic deupaz, reflecting the concept of vertical extent. Over time, "-th" solidified as a suffix to form nouns describing measurable or abstract qualities, giving "depth" its modern meaning of physical or metaphorical profundity.
