Pronouns tips and notes
The tips and notes for the pronouns skill introduces them primarily as alternatives to English "to be," instead of as, well, pronouns. This should be the very first focus. jIH means I, me, etc. Only once that concept is made clear should the "to be" use of pronouns be explained. Further, the "to be"ness of pronouns should not appear in the pronoun chart farther down the page: jIH doesn't mean "I am"; it means "I, me" and can be coupled with nouns to link "me" with the noun. This is a function of the coupling, not of the pronoun itself. The verbs in parentheses should be removed.
The lesson also says that pronouns may be left in sentences to emphasize, then gives an example sentence, jIqet jIH 'ach bIyIt SoH "I run but you walk." This kind of emphasis is achieved with -'e'. The kind of emphasis The Klingon Dictionary is talking about is the kind that clarifies: when a particular subject or object of a clause is not clear without an explicit pronoun, the pronoun will be used to make it clear.
For instance, if I say yIt, it's not at all clear who is running. If I say yIt chaH, now you know that "they run." Saying yIt chaH does not include any special focus on the chaH (you'd say chaH'e' for that); it's just clarifying. You mention this clarification in the next paragraph, but you're making it seem like this is a different function than the previous paragraph.
bIH is described as being for inanimate objects, but it's really for anything that doesn't use language. Factory robots are not capable of using language, but they are animate, and they are described with bIH.
