N added to Greek words ending in a short vowel to lengthen it “by position,” and “1” added to French
words beginning with a vowel, when they follow a word ending with a vowel (as si l'on for si on), is
called N or L “ephelcystic” (tagged-on); Greek, epi helko.

"ephelcystic" seems a word that might be fun to find a use for. Any volunteers?
