deepest
UK: ˈdiːpɪst | US: ˈdiːpɪst
adj. superlative form of "deep" (extending far down or in; profound in intensity or degree)
The word "deepest" combines the Old English root "dēop" (meaning "extending far down" or "profound") with the superlative suffix "-est," which originates from Proto-Germanic *-istaz. This suffix was used to form the highest degree of comparison in adjectives. Over time, "deep" retained its core meaning of physical or metaphorical depth, while "-est" became the standard marker for superlatives in English. The logic is straightforward: "deep" + "-est" = "the most deep."
