~ K ~
K. A letter borrowed by the English from the Greek alphabet. It has before all the vowels one invariable sound: as, keen, ken, kill; but is not much in use, except after c at the end of words: as, knock, clock, crack, back, brick, stick, pluck, check, which were written anciently with e final: as, clocke, checke, tricke. It is also in use between a vowel and the silent e final: as, cloke, broke, brake, pike, duke, eke. It likewise ends a word after a diphthong: as, look, break, shook, leek. The English never use c at the end of a word. K is silent in the present pronunciation before n: as, knife, knee, knell.
