Forms

κλῠ́ω (klúō) [1]

Etymology

It is inherited from Proto-Indo-European *ḱlew- (“to hear”).[2][1][3] The present κλύω is an innovation on the thematic root aorist ἔκλυον (ékluon), which has a Sanskrit counterpart in the verb Sanskrit श्रु (śru, “to hear”); both languages remade an older athematic aorist, still seen in the Homeric imperative κλῦθι (klûthi), whose exact counterpart is the Sanskrit imperative.[2] The verbal adjective κλυτός (klutós, “famous”) matches the Sanskrit participle “heard” and Latin inclutus (“famous”) from *ḱlu-tó-, while κλέος (kléos, “fame”) has the full grade.[2][1] Other languages made other presents, such as the Sanskrit nasal present.[2]

Ancient etymologists derived it from an unattested *κλῶ (*klô, “to make a sound”).[4]

Earliest recorded meaning

It is found from Homer on, of gods listening to prayers (“hear me”, κλῦθι) and of hearing words and news.[5][6]

Semantic evolution

It remained a poetic word: in comedy it appears only in mock tragic diction, and Aristophanes treats κλύειν and ἀκοῦσαι as the same thing.[6] In tragedy it also means to obey (a ruler, fate; a ship its rudder), and with an adverb to be spoken of, to have a good or bad name.[5][2] The present can have the sense of a perfect, “I have heard”.[5]

Timeline

  • Homer – The Iliad uses the imperative κλῦθι in prayers and the verb for hearing.[6][7]
  • 5th century BC – Tragedians use it for obeying and, with an adverb, for having a reputation.[5][2]
  • 5th–4th century BC – Aristophanes uses it only in mock tragic verse.[6]

  4. (present with perfect sense) To have heard, know.[5]
