nautical

Etymology

It is borrowed from Middle French nautique or its source borrowed from Latin nauticus (“of ships or sailors”), with the suffix -al added;^[2][3][4][5] Barnhart takes it from Latin, perhaps influenced by the French word,^[6] and Klein and Etymonline from the rare adjective nautic.^[7][5] The Latin adjective is from Ancient Greek ναυτικός (nautikós, “seafaring, naval”),^[2][8][9][7] from ναύτης (naútēs, “sailor”), from ναῦς (naûs, “ship”),^{[8][6][10][11]} from Proto-Indo-European *nāu- (“boat”), the root of navy and naval.^[8][5][6]

Earliest recorded meaning

Of or relating to sailing, sailors or the sea: 1552, in Huloet's Abcedarium Anglico Latinum.^[2][6][9]

Semantic evolution

The adjective has kept its first meaning, relating to ships, sailors and navigation.^[2][9][12] The nautical mile, a unit of distance of about one minute of latitude, takes its name from it.^[6] A noun nautical, a sailor or a writer on the sea, recorded from 1831, is now archaic and rare;^[2] the OED compares the Latin plural nauticī and Hellenistic Greek ναυτικός used as nouns for sailors.^[2]
