umlautlessness (uncountable)

  1. The fact or state of not exhibiting any signs of phonological umlaut.
    • 2012, Joseph Salmons, A History of German, page 136:
      As noted, the weak suffix -ita (< -iða) loses its vowel in long stems, creating this pattern of umlautlessness in long-stem preterit forms.
