k

The eleventh letter of the English alphabet and the eighth consonant, representing the voiceless velar plosive sound /k/. As a grapheme, 'K' is often silent when followed by an 'n' at the beginning of a word, as in 'knee' or 'knife'. It is less common than the letter C for representing the /k/ sound in English. It functions as an abbreviation for one thousand, a designation for potassium in chemistry, a unit of measurement for gold purity (karat), and the eleventh item in a sequence.
