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).
