From Ancient Greek διαίρεσις ‎(diaíresis, division, split), from διά ‎(diá, apart) + αἱρέω ‎(hairéō, I take).



diaeresis ‎(plural diaereses)

  1. (orthography) A diacritic ( ¨ ) placed over a vowel letter (especially the second of two consecutive ones) indicating that it is sounded separately, usually forming a distinct syllable, as in the English words naïve, Noël and Brontë, the French haïr and the Dutch ruïne.
  2. (linguistics, prosody) The separation of a vowel, often a diphthong, into two distinct syllables.
  3. (prosody) A natural break in rhythm when a word ends at the end of a metrical foot, in a line of verse.

Usage notes[edit]

  • The umlaut is an often visually identical diacritic which alters the sound of a single vowel (as in German schön). Properly speaking, the terms diaeresis and umlaut are not interchangeable, though speakers frequently use the term umlaut to refer to a diaeresis.

diaeresis f ‎(genitive diaereseos or diaeresis); third declension

  1. (grammar) diaeresis (division of a diphthong into two vowels in consecutive syllables)
    • (Can we find and add a quotation of Velius Longus to this entry?)
    • circa AD 384, Ser. Honoratus (aut.), G. Thilo & H. Hagen (eds.), In Vergilii Aeneidos commentarii in Servii Grammatici qui feruntur in Vergilii carmina commentarii II (1884), bk vii, l. 464 (p. 160, ll. 1–9):
      Fvrit intvs aqvai fvmidvs id est aquae amnis: nec inmerito; nam potest esse et alterius rei amnis, “ut fluvios videt ille cruoris”. Hanc autem diaeresin Tucca et Varius fecerunt: nam Vergilius sic reliquerat “furit intus aquae amnis” et “exuberat amnis”: quod satis asperum fuit. Notandum quod in toto Vergilio non reperiuntur nisi quattuor diaereses, hoc loco, et in tertio ⟨354⟩, ut “aulai medio libabant pocula Bacchi”, et in VI. ⟨747⟩ ut “aurai simplicis ignem”, et in IX. ⟨26⟩ “dives pictai vestis et auri”.
  2. (rhetoric) distribution
    • (Can we find and add a quotation of Julius Valerius Alexander Polemius to this entry?)
