U+03A5 "Υ" Greek Capital Letter Upsilon Unicode Character
U+03A5 "Υ" Greek Capital Letter Upsilon is the uppercase form of the twentieth letter of the Greek alphabet, which has a numeric value of 400 in the ancient Greek numeral system. Phonetically, in Classical Greek it represented a close front rounded vowel, like the French "u" or German "ü", but in Modern Greek it is pronounced as an "i" sound, similar to the English "ee". Historically, the letter has a distinctive graphical legacy, as it served as the direct ancestor of both the Latin letter "Y" and the Cyrillic letter "У", and its shape is often associated with the pitchfork or the letter's earlier Phoenician source, waw. In modern usage, it appears in academic contexts, such as mathematics and science where it denotes various quantities, and in the transcription of Greek words and names.
