P, or p, is the sixteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is pee (pronounced /ˈpiː/), plural pees.[1]
History
The Semitic Pê (mouth), as well as the Greek Π or π (Pi), and the Etruscan and Latin letters that developed from the former alphabet all symbolized /p/, a voiceless bilabial plosive.

English
In English orthography, ⟨p⟩ represents the sound /p/.
A common digraph in English is ⟨ph⟩, which represents the sound /f/, and can be used to transliterate ⟨φ⟩ phi in loanwords from Greek. In German, the digraph ⟨pf⟩ is common, representing a labial affricate /pf/.
Most English words beginning with ⟨p⟩ are of foreign origin, primarily French, Latin and Greek; these languages preserve the Proto-Indo-European initial *p. Native English cognates of such words often start with ⟨f⟩, since English is a Germanic language and thus has undergone Grimm's law; a native English word with an initial /p/ would reflect Proto-Indo-European initial *b, which is so rare that its existence as a phoneme is disputed. However, native English words with non-initial ⟨p⟩ are quite common; such words can come from either Kluge's law or the consonant cluster /sp/ (PIE: *p has been preserved after s).
P is the eighth least frequently used letter in the English language.
Other languages
In most European languages, ⟨p⟩ represents the sound /p/.
Other systems
In the International Phonetic Alphabet, ⟨p⟩ is used to represent the voiceless bilabial plosive.
Other uses
- A bold italic letter p is used in musical notation as a dynamic indicator for "quiet". It stands for the Italian word piano.[2][3]
