Solve Greek Phi Mazes Vol. III

Phi, pronounced [fi] in modern Greek, is the 21st letter of the Greek alphabet. In modern Greek, it represents [f], a voiceless labiodental fricative. In Ancient Greek it represented [p h], an aspirated voiceless bilabial plosive (from which English ultimately inherits the spelling "ph" in words derived from Greek). In the system of Greek numerals it has a value of 500 or 500,000. The Cyrillic letter Ef (F, f) arose from phi. Theta (Greek: Theta) is the eighth letter of the Greek alphabet, from this letter derived the Phoenician letter Teth. In the system of Greek numerals it has a value of 9. In Classical Greek Theta represented an aspirated voiceless dental plosive, but in Koiné and later dialects it became a voiceless dental fricative.
