  • 10th-century Byzantine: /ˈyp.ti.os/[1]

Forms

ῠ̔́πτῐος (húptios) m (feminine ῠ̔πτῐ́ᾱ, neuter ῠ̔́πτῐον); first/second declension[1]

Etymology

It is derived from Proto-Indo-European *upó (“below, under”) with the suffix *-tio-, which stayed productive in Greek, as in αἴτιος (aítios) and ἄρτιος (ártios).[2][1] The stem is that of ὑπό (hupó, “under”), ὑπέρ (hupér) and ὕπατος (húpatos).[3] Saussure set up an older *ὑπότιος (*hupótios).[3] Chantraine notes that the /t/ was not turned into /s/ before the /i/, perhaps to keep the word apart from the family of ὕψι (húpsi, “on high”), and that the role of the /t/ is unknown.[3][4]

The word has the same meaning as Latin supīnus (“lying on the back”), formed from the related sub (“under”).[3][2] Babiniotis also reports a view that it is a verbal adjective from the root of ὕπνος (húpnos, “sleep”), so that the word first meant someone sleeping on his back.[4]

Earliest recorded meaning

In the Iliad it is said of a man lying or falling on his back, the opposite of πρηνής (prēnḗs) “face down”: Achilles in his grief lies now on his side, now on his back, now on his face.[5][6][7]

Semantic evolution

From “on one's back” the word spread to anything turned upside down or with its hollow side up: an upturned helmet from which lots are shaken in Aeschylus, a shield laid face up in Aristophanes, the hand held out palm upwards to receive something.[6][8] Sophocles says of a man who suffers shipwreck that he sails with his benches upside down.[6] Aristotle calls the belly of an animal its ὕπτια parts, the side seen when it lies on its back.[6][3] Herodotus uses it of flat, level land, and Plato has “to swim on one's back”.[6][8]

Later it was used figuratively of people who are slack and careless, and of flat, tedious style; grammarians called the passive voice ὕπτιος.[6][2][3] Modern Greek keeps ύπτιος (ýptios) as a learned word, “lying on one's back”, also in the name of the backstroke.[9]

  • 5th century BC – Herodotus uses it of flat land.[6][10]
  • 5th–4th century BC – Plato uses “from the back” of swimming and of going through an argument backwards.[6][10]
  • 4th century BC – Aristotle calls the underside of an animal its ὕπτια parts.[6][10]
  • Modern Greek – Modern Greek ύπτιος (ýptios) survives as a learned word.[9][4]
