From Middle English fathome, fadom, fadme (“unit of length of about six feet; depth of six feet for nautical soundings; (loosely) cubit; ell”) [and other forms],[2] from 古期英語 fæþm, fæþme (“encircling or outstretched arms, bosom, embrace; envelopment; control, grasp, power; fathom (unit of measurement); cubit”) [and other forms], from Proto-West Germanic *faþm (“outstretched arms, embrace; fathom (unit of measurement)”), from Proto-Germanic *faþmaz (“outstretched arms, embrace; fathom (unit of measurement)”), from Proto-Indo-European *pet-, *peth₂- (“to spread out; to fly”).[3]
At sea, the fathom is exclusively a measure of water depth. Therefore, a boat 100 fathoms offshore is not 600 feet from the shore, but rather at the nearest point to shore where the water depth is 600 feet.
From Middle English fathmen, fadmen (“to encircle (something) with the arms, embrace; to feel, grope; to measure by the ell (または perhaps the fathom)”) [and other forms],[4] from 古期英語 fæðmian, from Proto-Germanic *faþmōjan, from *faþm (“outstretched arms, embrace; fathom (unit of measurement)”):[5] see further at etymology 1.
