Mandaic At and Hebrew Tav occupy the same place in the twenty-two letter Aramaic sequence. Hebrew keeps the inherited noun as the letter name and the numeral value 400; Mandaic keeps neither. Where the Mandaic shapes came from is disputed, a cursive Aramaic hand or the Parthian chancery script.

Cognate letters. Arabic ta and Hebrew tav both continue the twenty-two letter Northwest Semitic alphabet, and they hold the same place in the inherited order and the same numeral value, 400. Neither is derived from the other.

Samaritan Taaf and Hebrew Tav are cognates. Both continue the same Paleo-Hebrew sign, both write plain t, both close the sequence and both carry the value 400, the highest any single letter holds.

Greek Tau and Hebrew Tav are cognates. Both continue the same Phoenician sign, which is why both carry the numeral value 400 in their letter-number systems. A shared ancestor, not a borrowing in either direction. The Greek alphabet was adapted from the Phoenician abjad in the early first millennium BC, and the Hebrew square script descends from the same abjad through Aramaic.

Syriac Taw and Hebrew Tav stand at the same place in the twenty-two letter Aramaic sequence and carry the same letter-numeral value, 400. The Syriac script grew out of the local Aramaic cursive of Edessa and the Hebrew square script out of the same Aramaic alphabet, so the two letters are inherited from one ancestor rather than borrowed from each other.

Both signs continue the same Northwest Semitic consonant inherited from a shared abjad ancestor; this is a cognate correspondence, not a borrowing in either direction. Ugaritic and Hebrew share the same twenty-two-consonant core, with Ugaritic adding six further signs Hebrew never developed separately.

Tawe and the Hebrew tav continue the Semitic plain t. Tav closes the Hebrew order, where tawe stands tenth in the Ge'ez one.
