Ƥ
The letter Ƥ, called P with hook, is a letter of the Latin alphabet based on the letter p. It is used in some alphabets of African languages such as Serer.
The minuscule ƥ was formerly used in the International Phonetic Alphabet to represent a voiceless [bilabial implosive]. It was withdrawn in 1993.
The minuscule variant resembles a lowercase thorn.
