Forms

λῡ̆́ω (lū́ō) [1]

Etymology

It is inherited from Proto-Indo-European *lewH- (“to cut off, loosen”), which Beekes reconstructs as Proto-Indo-European *lh₁u-, perhaps a u-present of Proto-Indo-European *leh₁-.[1][2][3] The Greek verb system is the result of levelling: the Homeric athematic aorist λύμην (lúmēn), λύτο (lúto), with a short vowel, is archaic, and the thematic present λύω is newer.[2][4] Its vowel was short in Homer and became long in Attic, probably after the aorist λῦσαι (lûsai).[2][5]

Cognate with Latin luō (“to atone, pay”), to which solvō (“to loosen, release”) belongs, from *seluō; the long vowel of solūtus and of a Sanskrit participle meaning “cut off” agrees with that of Greek βουλυτός (boulutós) and points to a laryngeal in the root.[2] Further cognates are Sanskrit लुनाति (lunā́ti, “to cut off, sever”) and Lithuanian liáuti (“to stop”), and, with an s-extension, English loose and lose.[1][2]

Earliest recorded meaning

It is found from the opening of the Iliad, where the priest Chryses comes to the ships to ransom his daughter (the middle, λυσόμενος).[6][7] Homer uses it of undoing a belt or armour, unyoking horses, releasing prisoners for ransom, dismissing an assembly and settling quarrels; when a warrior's knees or limbs are “loosened”, his strength fails and he falls or dies.[8][7]

Semantic evolution

From “loosen” the verb came to mean “dissolve, break up, destroy”: buildings are pulled down, laws and treaties annulled, and difficulties or riddles solved.[9][7] Chantraine notes that it sometimes means “be useful”, like λυσιτελέω (lūsiteléō), and the active is used intransitively for “it pays”.[5][9] The middle means “to pay, expiate”, and in medicine the passive is used of the bowels being emptied.[9] The Atticist lexica note that “to ransom” takes the price in the genitive.[10]

In the Septuagint it is used of untying sandals and opening sacks, of setting free and of destroying.[11] In the New Testament Jesus says “destroy this temple” with λύω, and the pairing with δέω (déō, “to bind”), “binding and loosing”, is the power given to the disciples.[12][13]

Medieval vernacular Greek used both λύω and the newer present Byzantine Greek λύνω (lúno).[14] In Modern Greek the everyday verb is λύνω (líno); Modern Greek λύω (lío) is a learned word.[15][16]
