The word for "no"
The lesson description for "Dialogue I" reads in part:
The words HISlaH and ghobe'
HISlaH means "yes" and ghobe' means "no". These words are primarily used to answer yes/no questions. Later in the course, you will learn another word - Qo' - which is used to express refusal (as in "No, I won't!").
Note that unlike the English word "no", this word cannot be used as a determiner (as in "We have no bananas."), nor as an adverb ("I am no better."); it is strictly used as an exclamation.**
Does the second paragraph refer to ghobe', to Qo' or to both words?
