Etymology

According to the OED, which revised the entry in 2012, it is inherited from Middle English afte (“back”),[2][3][4][5] inherited from Old English æftan (“behind, from behind”),[2][4][5][6][7] from Proto-Germanic *aftanē (“from behind”).[8] The Old English adverb is cognate with Old Frisian efta (“behind”), Old Saxon aftan, Old High German aftan (“from behind”), Old Norse aptan (“from behind, behind”) and Gothic 𐌰𐍆𐍄𐌰𐌽𐌰 (aftana, “from behind”),[2][5][7][8] all formed with an adverbial suffix from the Germanic base of 𐌰𐍆𐍄𐌰 (afta, “behind, past”), of uncertain and disputed origin.[2] The OED notes that this base can perhaps be traced to the Indo-European base of Ancient Greek ἐπί (epí), so it cannot certainly be called cognate with after, although the two were probably felt to be related from an early date.[2] Etymonline instead takes the Old English word as a superlative formed on of (“away, off”), from Proto-Indo-European *apo- (“off, away”),[9] and the American Heritage Dictionary also refers it to that root.[4] Other Oxford dictionaries take the nautical word of the 17th century as probably an alteration of abaft or baft under the influence of Low German achter (“abaft, after”) and achter,[10][11][12] and Collins calls it perhaps a shortening of abaft.[13] The OED finds the word apparently unrecorded between the early 14th and the late 16th centuries.[2]

Earliest recorded meaning

Behind, in the rear; from behind: in the Old English Battle of Brunanburh, in the Parker manuscript of the Chronicle,[2] which Barnhart dates 937 and where the eagle is described as "white behind".[5][6]

Semantic evolution

The Old English senses "behind" and "later, afterwards" died out,[2] and in Middle English the word survives in the phrase on afte, to the rear or backwards, recorded about 1335.[2][3] When it reappears about 1580 it is a sailors' word: in or near the stern of a ship, and after 1669 also towards the stern.[2] Later it was extended to the rear of aircraft and spacecraft,[2][4] and Etymonline calls it now purely nautical.[9] Its use as an adjective, of the rear part of a ship, is recorded from 1711 in the OED,[2] while Merriam-Webster dates the adjective to 1667.[7] In north Yorkshire dialect aft meant backward in a figurative sense, and aftest the hindmost or laziest of a group.[14]
