Teth

The Phoenician letter name ṭēth may mean "spinning wheel"[2] pictured as (compare Hebrew root ט-ו-י meaning 'spinning' (a thread) which begins with Teth). According to another hypothesis (Brian Colless), the letter possibly continues a Middle Bronze Age glyph named ṭab 'good', Aramaic טַב 'tav', Hebrew טוב‎ 'tov', Syriac ܛܒܐ 'tava', modern Arabic طَيّب 'ṭayyib', all of identical meaning, whose picture is based on the Nefer 'good' hieroglyph common in ancient Egyptian names (e.g. Nefertiti):

Jewish scripture books about the "holy letters" from the 10th century onward discuss the connection or origin of the letter Teth with the word tov "good". This was especially emphasized ever since the late 1600s after the Baal Shem Tov became influential, since the letter Teth was in his Acronym standing for Tov, and goodness was part of his philosophy. The acrostic poems of the Bible use 'Tov' to represent the letter (e.g. Psalm 119:65-72).

The letter is named ṭāʾ  طَاءْ; Modern Standard Arabic pronunciation: /tˤ/.

The Hebrew spelling of name of the letter: טֵית‎

A symbol similar to the Phoenician teth is used for the tensor product, as ${\displaystyle \otimes }$, but this is presumably an independent development, by modification of the multiplication sign ×. The Hebrew ט‎ is also visually similar to the letter Ʋ.
