Usage notes

  • ad-, when used as an augment affix, vanishes in prototonic forms due to syncope. However, its presence may be detected via the different syncope patterns between forms augmented with ad- and those that were not.
  • In deuterotonic verbs where ad- is the first prefix and the next sound is /t/, the d in the prefix may be dropped in its spelling.
