The Letter C; Sentimental or Redundant?

From the Archives:

Today on the "Ian's damaged mind" channel we will be examining the letter C.

While the English language is full of contradictions, rules, exceptions to those rules and stolen grammar and vocabulary the letter C has to be one of the greatest wastes. I recall several years ago there was an e-mail joke passed around dealing with the European Union adopting English as its official language (as opposed to French or German). It then went through a five year process of adapting the language to European usage by simplifying the grammar and eliminating redundant letters and letter combinations. In the end they had essentially turned English into German.

But that just serves to underscore the true redundancy of C. After all, what does a C sound like? Most will tell you that a "hard C" sounds like a K and a "soft C" sounds like an S. Based on that information is there ANY word in the language where C cannot be replaced with K or S? I have yet to find any... if you do please let me know.

Please note: Arguments that a certain (sertain?) word "looks funny" or "doesn't parse well" will not be accepted (aksepted?). That is just a side effect of having looked at them in their current (kurrent?) format for 30+ years.

Lucky, you just get to listen to my ramblings on occasion then delete them from your inboxes. I have to live inside this brain 24x7....
