Why we can't learn Pohnpeian

I finally received my missionary name tag written in Pohnpeian.  Take a good look at the name of our church.  The Church of Jesus Christ of Latter-Day Saints.  Sounds easy enough.  Now see if you can say it in Pohnpeian.  We just don't seem to be able to put those letters together and get it from the brain out the tongue.  The young elders and sisters figure it out rather quickly but we don't catch on nearly as fast.
