Forms

θείνω (theínō) [1]

Etymology

It is inherited from Proto-Indo-European *gʷʰen- (“to strike, slay”), as a full-grade present with the suffix *-ye-.[2][3][1] Wiktionary gives the Proto-Hellenic form as *kʷʰéňňō, from *gʷʰén-ye-ti, and notes the alternative proposal of the linguist Andreas Willi, who takes θείνω as formed secondarily from an older present *θένω (thénō).[1] Frisk and Beekes compare Lithuanian geniù (“to lop off branches”), which matches it exactly in form.[4][2]

The root is better preserved in an athematic present: Sanskrit हन्ति (hánti), Avestan jainti and Hittite kuenzi, all “he strikes, kills”, from *gʷʰén-ti.[2][3][4] Latin has it, with a suffix in -d-, in Latin dēfendō and offendō.[2][3] Other cognates are Old Armenian ջնեմ (ǰnem, “to slay”) and Old English bana (“slayer, bane”).[1][2] Chantraine explains the sense “to kill” as a euphemism, “to strike down”.[3] In Greek the same root gives the reduplicated aorist ἔπεφνον (épephnon, “I slew”) and the noun φόνος (phónos, “murder”).[4][1][2]

The lexicon of Zonaras glosses it as τύπτω (túptō, “to strike”).[5]

Earliest recorded meaning

It is a Homeric verb for striking: the Iliad has the passive of a person being beaten (1.588), and uses the active of striking someone on the neck with a sword (20.481) and of driving horses with the whip (17.430).[6][7]

Semantic evolution

It remained a poetic word.[7] Pindar uses it of a blow with a staff, and Aeschylus of ships ramming one another, of drowned men dashed against the shore, and figuratively of lashing someone with taunts.[8][7] Euripides and Aristophanes have a second aorist, θενεῖν, made secondarily on this present, and Aristophanes a future θενῶ.[3][7] The reduplicated aorist ἔπεφνον (épephnon), which belongs to the same verb, kept the old sense “to kill, slay”.[8][3]

Papyros describes the present as rare and poetic.[9]
