Etymology
The letter Q originates from the Phoenician letter qoph, which represented a “knot” or “cord.” It was adopted by the Greeks as koppa and later by the Romans in the Latin alphabet. Q became the seventeenth letter of the English alphabet and typically represents the voiceless uvular stop sound (/kʷ/), as in “queen.” In modern English, Q is almost always followed by the letter U.
