I had no idea (and I'm pleasantly surprised to find out) that Swahili had so many Arabic-based words! That certainly makes this a little easier.

As far as we learned at university 80% of loanwords in Swahili are based on Arabic. (now more and more English too, but so far...)

It told me "tafadhali" was wrong, then told me the correct answer is "tafadhali"
