Thaa, much like Thee

The fourth letter, Thaa, can be compared to the sound that you make saying "th". One important thing to note, is that Baa, Taa, and Thaa, look similar in the shape of the letter. The only thing that differs them from each other, are their dots. Baa has one dot underneath, Taa has two dots above, and Thaa has 3 dots above.
