  • Note that this is not simply -able + -ity: in English it is a parallel formation, not a compound suffix: there is a sound and spelling change. Compare -ably (compound suffix) and -ification (parallel suffix).
  • Some words ending in -ability are alterations of words of French origin ending in -abilité or Latin words ending in -abilitās.
