Variations on written form and pronunciation

The letter tav is one of the six letters that can receive a dagesh kal diacritic; the others are bet, gimel, dalet, kaph and pe. Bet, kaph and pe have their sound values changed in modern Hebrew from the fricative to the plosive, by adding a dagesh. In modern Hebrew, the other three do not change their pronunciation with or without a dagesh, but they have had alternate pronunciations at other times and places.
In traditional Ashkenazi pronunciation, tav represents an without the dagesh and has the plosive form when it has the dagesh. Among Yemen and some Sephardi areas, tav without a dagesh represented a voiceless dental fricative —a pronunciation hailed by the Sfath Emeth work as wholly authentic, while the tav with the dagesh is the plosive.

In Judaism

Tav is the last letter of the Hebrew word emet, which means 'truth'. The midrash explains that emet is made up of the first, middle, and last letters of the Hebrew alphabet. Sheqer, on the other hand, is made up of the 19th, 20th, and 21st letters.
Thus, truth is all-encompassing, while falsehood is narrow and deceiving. In Jewish mythology it was the word emet that was carved into the head of the Golem which ultimately gave it life. But when the letter aleph was erased from the golem's forehead, what was left was "met"—dead. And so the golem died.
Ezekiel 9:4 depicts a vision in which the tav plays a Passover role similar to the blood on the lintel and doorposts of a Hebrew home in Egypt. In Ezekiel's vision, the Lord has his angels separate the demographic wheat from the chaff by going through Jerusalem, the capital city of ancient Israel, and inscribing a mark, a tav, "upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof."
In Ezekiel's vision, then, the Lord is counting tav-marked Israelites as worthwhile to spare, but counts the people worthy of annihilation who lack the tav and the critical attitude it signifies. In other words, looking askance at a culture marked by dire moral decline is a kind of shibboleth for loyalty and zeal for God.

Sayings with taf

״מאל״ף עד תי״ו״, "From aleph to taf" describes something from beginning to end, the Hebrew equivalent of the English "From A to Z."

Syriac taw

In the Syriac alphabet, as in the Hebrew and Phoenician alphabets, taw or tăw is the final letter in the alphabet, most commonly representing the voiceless dental stop and fricative consonant pair, differentiated phonemically by hard and soft markings. When left as unmarked or marked with a qūššāyā dot above the letter indicating 'hard' pronunciation, it is realized as a plosive. When the phoneme is marked with a rūkkāḵā dot below the letter indicating 'soft' pronunciation, the phone is spirantized to a fricative. Hard taw is Romanized as a plain t, while the soft form of the letter is transliterated as ' or '.
