Pronunciation

  • 5th-century BC Attic: /lan.tʰá.nɔː/[1]
  • 4th-century AD Koine: /lanˈθa.no/[1]
  • 10th-century Byzantine: /lanˈθa.no/[1]

Forms

λᾰνθᾰ́νω (lanthánō) [1]

Etymology

It is inherited from Proto-Indo-European *leh₂- (“to remain hidden”), with a dental extension.[2][1] The oldest forms of the system are the full-grade present λήθω (lḗthō), Doric λάθω (láthō), and the zero-grade aorists λαθεῖν (latheîn) and λελαθεῖν (lelatheîn); the nasal present λανθάνω, rarer than the full-grade present in Homer, is probably a later formation after μανθάνω (manthánō) : μαθεῖν (matheîn).[2][3][4] Wiktionary instead derives it from a nasal-infixed *lh₂-n-dʰ-.[1]

As in πύθω (púthō) beside πύον (púon), the -θ- may be a present suffix; a form without it seems to survive in the Hesychius gloss λῆτο (lêto, “forgot”).[2][3][4] The nearest cognate is Latin lateō (“to be hidden”), with a different suffix.[3][2][5] Related Greek words are λήθη (lḗthē, “forgetfulness”), λάθρα (láthra, “secretly”) and ἀληθής (alēthḗs, “true”).[2][5]

Earliest recorded meaning

It is found from Homer on, at first mostly as λήθω: to escape notice, and in the middle to forget.[2][6] The Iliad already has the construction with a participle (to do something unnoticed), and the Odyssey has “it did not escape me, who know much” (9.281).[6][5]

Semantic evolution

The construction with a participle became one of the most characteristic idioms of Greek: “he escaped notice doing it” for “he did it without being seen”, and, with the person in the accusative, “it escaped the notice of”.[6][7] Herodotus and Aristophanes use it reflexively, “to fail to realise that one is doing something”.[6] The middle meant to forget, with a genitive.[6]

The New Testament uses it of being hidden and escaping notice.[8] Modern Greek has it as a learned word, Modern Greek λανθάνω (lantháno), to escape notice or to forget.[9] The chemical element lanthanum was named from it in 1841 because it lay “concealed” in the earth from which it was extracted.[10]
