English spelling can be simplified not just by spelling words phonetically but by changing the use of some consonants. This can erase the history and origin of words in ordinary writing but English is documented from Late Antiquity on.
C should be used only for the CH sound as in church, which would be written curc. Other spellings would be cop for chop, camp for champ, ciken for chicken.
