Teth, also written as Ṭēth or Tet, is the ninth letter of the Semitic abjads, including Phoenician ṭēt 𐤈, Hebrew, Aramaic ṭēṯ 𐡈, and Syriac ṭēṯ ܛ, and Arabic ṭāʾ ط. It is also related to the Ancient North Arabian 𐪗, South Arabian 𐩷, and Geʽez ጠ.
The Phoenician letter also gave rise to the Greek theta (Θ), originally an aspirated voiceless dental stop but now used for the voiceless dental fricative. The Arabic letter (ط) is sometimes transliterated as Tah in English, for example in Arabic script in Unicode.
