Rho (upper case Ρ, lower case ρ) is a letter of the Greek alphabet. See Rho (letter). The Greek alphabet (Greek: ) is an alphabet consisting of 24 letters that has been used to write the Greek language since the late 8th or early 9th century BC. It was the first alphabet in the narrow sense, that is, a writing system using a separate symbol for each vowel...
