P \P\ (p[=e]),
   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 Ph[oe]nician, 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}. See Guide to Pronunciation,
   [sect][sect] 247, 248, and 184-195.
