Synonyms

In addition to the well-known 120 words, pu lists the following 3 words as "synonyms":

• kin as a synonym of a
• namako as a synonym of sin
• oko as a synonym of lukin

Those words have been in use before and since the publication of pu, but with different meanings from their supposed relatives. Calling them "synonyms" was a deliberate attempt to merge them. ku acknowledges that the words have retained their separate meanings among those who use them.
