Shart

Unfortunately for Swahili speakers – the word shirt is shati in Swahili and so their English pronunciation for shirt comes out as shart.  In addition to that, since it sounds like shart in their head, they also spell it this way.  Now maybe some of you also don’t know what a shart is and I urge you to check it out on urbandictionary.com to see why this is so funny to read on their homework.  Some good sentences I’ve gotten:
Do you have a shart?
The shart is soft.
I like sharts. 
Recently, not only because of shirt/shart that I have started to stress the importance of pronunciation, but also because when you have a class of 60 kids trying to say the word “fork”, it definitely sounds like a chorus of profanity coming back at you.
