The last (i.e., 22nd) letter of the Hebrew alphabet is “Tav,” which has the sound of “t” as in “tall.”
In modern Hebrew, the letter Tav can appear in three forms:
Write the manual print version (or "block" version) of Tav as follows:
Note that the first stroke overhangs the second stroke, and that the second stroke has a small “foot” that goes to the left.
And the cursive version:
This letter is similar to the print version except that the first stroke slopes down from the top right to the baseline.
Write the letter Tav (from right to left) in both manual print and script several times:
Note: The letter Tav can also take a dot, or dagesh mark. In ancient Hebrew, a Tav without the dot was pronounced “th” (e.g., as in Sabbath). In the Ashkenazi tradition, Tav without the dot is pronounced “s” (as in “Shabbos”), but in modern Hebrew, Tav with or without the dagesh is pronounced simply as “t.”
