Taw

Taw, tav, or taf is the twenty-second and last letter of the Semitic abjads, including Arabic tāʾ ت‎, Aramaic taw 𐡕‎, Hebrew tav ת‎, Phoenician tāw 𐤕, and Syriac taw ܬ. In Arabic, it also gives rise to the derived letter ث ṯāʾ. Taw's original sound value has been claimed to be /t/. It is related to the Ancient North Arabian 𐪉‎‎‎, South Arabian 𐩩, and Geʽez ተ. The Phoenician letter potentially gave rise to the Greek tau (Τ), Latin T, and Cyrillic Т.
