   P () the sixteenth letter of the English alphabet, is a nonvocal
   consonant whose form and value come from the Latin, into which language
   the letter was brought, through the ancient Greek, from the Phoenician,
   its probable origin being Egyptian. Etymologically P is most closely
   related to b, f, and v; as hobble, hopple; father, paternal; recipient,
   receive. See B, F, and M.
