C.
C has before e and i the sound of s; as sincerely, centrick, century, circular, cistern, city, siccity: before a, o, and u, it sounds like k, as calm, concavity, copper, incorporate, curiosity, concupiscence.
C might be omitted in the language without loss, since one of its sounds might be supplied by, s, and the other by k, but that it preserves to the eye the etymology of words, as face from facies, captive from captivus.
Ch has a sound which is analyzed into tsh, as church, chin, crutch. It is the same sound which the Italians give to the c simple before i and e, as citta, cerro.
Ch is sounded like k in words derived from the Greek, as chymist, scheme, choler. Arch is commonly sounded ark before a vowel, as archangel, and with the English sound of ch before a consonant, as archbishop.
Ch, in some French words not yet assimilated, sounds like sh, as machine, chaise.
C, according to English orthography, never ends a word; therefore we write stick, block, which were originally, sticke, blocke. In such words c is now mute.
It is used before l and r, as clock, cross.
