/tav/ · 22/22
Tav seals the Hebrew alphabet in 22nd and final place. In Lepdy, children tap it, hear its 't' sound, and discover words that begin with it like 'tapuach' (apple), 'toda' (thank you) and 'tut' (strawberry) — completing all the letters.
Tav makes a 't' sound as in 'tapuach' (apple), the same sound as the letter Tet.
Yes, Tav is the 22nd and final letter of the Hebrew alphabet.
