Etymology
The letter P originates from the Phoenician letter pe, which symbolized a “mouth.” It was adopted by the Greeks as pi and later by the Romans in the Latin alphabet. P became the sixteenth letter of the English alphabet, typically representing the voiceless bilabial plosive sound (/p/), as in “pen.”
