Transliteration. The letter
Tet is transliterated "t".
(purity, purification) is transliterated tohora. Syllabication. to-ho-ra.
Note: The pronunciation of tohora is trucky. The vowel after tet is a kamats ḥatuf not a kamats; it is an open unaccented syllable but a short vowel. [This is because the gutteral letter (hey) that follows cannot take a sh'va and so demands a compond sh'va.] So... "to" not "ta" and the vowel after hey, a compound sh'va, is a ḥatuf kamats, so is a very short "o."]
