That said, there is some official commentary from Okrand regarding syllable emphasis:

For the possessive suffixes, however, this doesn't work. {jaghna'lI'} means "definitely your enemy (and not your friend, etc.)." It doesn't specifically mean "definitely your enemy (and not mine)."

He said if you want to emphasize the possessor, just give it extra stress when saying the word: {DujlIj} (or DujlIj or DujlIj or DujlIj or DujLIJ or however you want to transcribe it -- I'm not sure whether italics and bold and all of that will show up for you).

I knew that Okrand had commented on emphasized syllables. I couldn't remember where.

Now mayqel is going to ask us about -na' not applying to -lI'... :D
