yea you english people complicate matters
for example
you write fish where sh could be simplefied fi (the sound that sh makes in fish is in our alphabet)
or chill where the sound of ch is the letter č in our abc čill
the same goes whit shit we have for the sh sound
and then we have i dunno if english produces that sound
athough we have some same problems like the English language the Serbs simplified it even more they write "pii kao to govori" (write like you say it) they do not use dubble letters or any substitute letters (like your c) if it sound like a k they write it whit a k.
