Nu (letter)

From Wikipedia, the free encyclopedia

Nu (/ˈnj/; uppercase Ν, lowercase ν; Greek: ni [ni]) is the thirteenth letter of the Greek alphabet, representing the voiced alveolar nasal IPA: [n]. In the system of Greek numerals it has a value of 50. It is derived from the ancient Phoenician language nun . Its Latin equivalent is N, though the lowercase () resembles the Roman lowercase v.

The name of the letter is written νῦ in Ancient Greek and traditional Modern Greek polytonic orthography, while in Modern Greek it is written νι [ni].

Letters that arose from nu include Roman N and Cyrillic Н.
