What Is the Etymology of the Word Fathom?

The word fathom has been used since the Middle English fadme, Middle English fathome, and Middle English fathme, which referred to an embrace and the lap, breast, or womb. 

This word comes from the Old English fæþm and Old English fæthm, which means “outstretched arms.” Since the word fathom is used as a term of measurement to mean six feet, it makes sense that this would be roughly the measurement of the distance from fingertip to fingertip if a man’s arms were outstretched.

The Old English term comes from the cognates in the German faden, Old Frisian fethem, Danish favn, Dutch vadem, Icelandic faðmur, Swedish famn, Low German fadem, Old Norse fathmr, and Old High German fadum

Fathom has Proto-Germanic and Proto-Indo-European roots. Other ancient variations on fathom include fæþme, faþmaz, fadome, vaam, and faem. These come from the Latin patēre and pandere, as well as the Greek petannynai.

Fathom was originally used as a verb to mean to embrace. By the 1600s, it was used as a form of measurement at sea and a verb meaning to measure by a sounding line. Its alternate meanings also developed around this time.
