Etymology

The word "in-depth" combines the preposition "in," meaning "into," with "depth," derived from Old English "dēop" (deep) + the noun-forming suffix "-th." Originally used literally ("into the deep"), it evolved figuratively by the early 20th century to describe comprehensive analysis or coverage, emphasizing penetration beyond surface-level understanding.
