Phi (/faÉª/; uppercase Ï, lowercase Ï or Ï; Ancient Greek: ÏÎµá¿ pheÃ®; Modern Greek: ÏÎ¹ fi ) is the 21st letter of the Greek alphabet. In Ancient Greek, it represented an aspirated voiceless bilabial plosive (), which was the origin of its usual romanization as ph.
Phi is also used as a symbol for the golden ratio and on other occasions in math and science. This use is separately encoded as the Unicode glyph Ï. The modern Greek pronunciation of the letter is sometimes encountered in English (as /fiË/) when the letter is being used in this sense.
