π€ in the context of Mu (letter)
Mu (/Λm(j)uΛ/ ; uppercase Ξ, lowercase ΞΌ; Ancient Greek ΞΌαΏ¦ [mΕ·Λ], Greek: ΞΌΞΉ or ΞΌΟ βboth [mi]) is the twelfth letter of the Greek alphabet, representing the voiced bilabial nasal IPA: [m]. In the system of Greek numerals it has a value of 40. Mu was derived from the Egyptian hieroglyphic symbol for water, which had been simplified by the Phoenicians and named after their word for water, to become π€ (mem). Letters that derive from mu include the Roman M and the Cyrillic Π, though the lowercase resembles a small Latin U (u).
