In ancient Greek grammar, movable nu, movable N or ephelcystic nu (Ancient Greek: νῦ ἐφελκυστικόν nû ephelkystikón, literally "dragged-in nu") is a letter nu (written ν; the Greek equivalent of the letter n) placed on the end of some grammatical forms in Attic or Ionic Greek. It is used to avoid two vowels in a row (hiatus) and to create a long syllable in poetic meter as a form of epenthesis.
