Use in writing systems
In English orthography and most other European languages,  represents the sound .
A common digraph in English is , which represents the sound , and can be used to transliterate  phi in loanwords from Greek.
In German, the digraph  is common, representing a labial affricate .
Most English words beginning with  are of foreign origin, primarily French, Latin, Greek, and Slavic; these languages preserve Proto-Indo-European initial *p.
Native English cognates of such words often start with , since English is a Germanic language and thus has undergone Grimm's law; a native English word with initial  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  are quite common; such words can come from either Kluge's law or the consonant cluster  (PIE *p has been preserved after s).
In the International Phonetic Alphabet,  is used to represent the voiceless bilabial plosive.
Music
