[Lingtyp] Apostrophe highlighting morphological information

[Jeff Siegel]

Greetings:

I'm posting a question from a colleague in Germany:

do you know of any language where the apostrophe represents a glottal
stop and where it highlights morphological information? that is, the
apostrophe (the glottal stop) only occurs at word-initial or word-final
position or at morpheme boundaries. it would be great if you could give
me an example. unfortunately i could not find any in the literature. 

Grateful for any replies.

Thanks,
Jeff
