au (uppercase Τ, lowercase τGreek: ταυ[taf]) is the 19th letter of the Greek alphabet. In the system of Greek numerals it has a value of 300. The name in English is pronounced /taʊ/ or /tɔː/,[1] but in modern Greek it is [taf].[2][3] This is because the pronunciation of the combination of Greek letters αυ has changed from ancient to modern times from one of [au] to either [av] or [af], depending on what follows (see Greek orthography). Tau was derived from the Phoenician lettertaw (𐤕).[4] Letters that arose from tau include Roman T and Cyrillic Te (Т, т). The letter occupies the Unicode slots U+03C4 (lowercase) and U+03A4 (uppercase). In HTML, they can be produced with named entities(τ and Τ), decimal references (τ and Τ), or hexadecimal references (τ and Τ).
