So I could give you more vocab words to memorize, but that would be boring. Instead, I'll show you how to make up new words as you go. The regular noun endings use "k" at the end. The regular verb endings use "p" at the start. If you are adapting a word into komLang, that's not in the official word lists, or whatever change the regular noun ending to "p" and the regular verp ending so it uses k and surround and preceed the new word with the special ending.

Thus you'd define a "local variable" that would be used for the rest of the conversation.
