The word "fathomless" is derived from the noun "fathom", which refers to a unit of measurement used to determine the depth of water. The term originates from Middle English "faden" or "fadme", which ultimately come from Old English "fæðm", meaning "outstretched arms" or "embrace". This Old English word is related to the Old Norse "faðmr", which has a similar meaning. Over time, the term "fathom" came to specifically represent a measurement of depth, and the adjective "fathomless" was formed to describe something immeasurable or unfathomable.
