If there is an "ih" "or "ee" vowel sound (i, e, or y) at the start of the word, it will start with a K and not a C. When a C is followed by an I, E, or Y, it usually takes on an "S" sound. (City, celery, cyan.) So the "K" sound of the letter C is exclusive to words beginning with C and followed by the vowels A, O, or U or blended as CL or CR. (Cat, Cot, Cut, Class, Crass) The digraph CH has an entirely distinct sound of its own.
Generally, you start off with the letter C.
