The letter C leads to a lot of pronunciation mistakes. This is because C can be pronounced two different ways.
C can be pronounced as:
S in CITY
K in CAT
How can you tell which pronunciation to use? Just follow these rules:
If the letter C comes before I, E, or Y, then pronounce the letter C as an S sound.
If the letter C comes before A, O, or U, then pronounce the letter C as a K sound.
