Topic: New words

How does one introduce new words? I have coined these word's (for Svartiska but could be used in other dialects): okh "knee" (from  Quenya "occa"); kahosh "liver" (derivative prefix ka- + "hosh" guts"), gât- "to lie (down)" (from Quenya caita-) [I know that the last one is kât- in LoS also from Q. caita-].
