There is a class of words in Mirad which are called hybrids, i.e. cross-combinations of opposite words that mean something and something else or something or something else. For example, in English, swinging is "moving BACK-AND-FORTH", or, questions can be of the type "YES-OR-NO". The vowels in these directionals are, for euphonic purposes, ao, eo, or ui. These alternating expressions are often used as adverbs or verbal prefixes. Here is an incomplete list of such expressions, the elements decomposed, and examples of their usage:

1This is a long form of yeb (in) that contrasts with oyeb (out).
Keep in mind that if a hybrid word ends in b, the b assimilates by dropping from per (to go) and ber (to put) words, eg:
  • aob + ber = aober
  • uib + per = uiper
