Ideally, yes. So a word like qostiid would ideally be pronounced like "quo-steed," qahnaarin like "qua-nar-in." This doesn't always happen with the in-game pronunciations but it's a good rule of thumb to help differentiate "q" from "k."

For invented words, what this means is that "q" shouldn't be used to end words or syllables. For example, a word like paaq wouldn't be typical. Rather, it'd be paak. In a word like sahqo "red" it works because it's at the beginning of a syllable.
