The /k/ sound is spelled with <c>, <k> or <qu> pronounced /kw/ initially, and <ck> or <ke> medially or finally. Two exceptional spellings are <qu> in pique and <ch> in Reich, though many English speakers will use a fricative in the latter. The /s/ sound is normally spelled with <s> or <c> initially. Medially or finally there are many spellings, including <ce>, <sce>, <s> and <ss>. There are also oddities like inital <ps> in psalm. Notice who the homograph bass makes pairs with back and bake, and close with cloak and slows.
The /s/ sound also occurs in the letter name C. An interesting sidelight on this is brought out by the work of David Cargill, the missionary who worked out the orthography of Fijian in the 1830s. Using <k> for /k/ and <s> for /s/, he used <c> for /Ɵ/, for which his memory was subsequently blessed by Fijian schoolchildren learning to read and cursed by colonial administrators. There is a legend, plausible but unsupported by any documentary evidence, that he asked his printer for Greek thetas, and the printer told him he didn't have any but he did have leftover cases of letter C.
The contrast is between a velar stop and an alveolar fricative, both voiceless. It causes no problems in itself, although the inconsistent spelling of words with /s/ may give rise to errors.
