Rabbi Mordechai Kraft
1) Hebrew is written and read right to left.
2) Like English with its 2 forms to the alphabet, an upper and lower case version, Hebrew has a "block and a cursive script." Sometimes this Rabbi mixes both forms when writing a single word, which can easily be confusing.
3) There are 22 letters in Hebrew, each is a consonant. Vowels are not considered as letters, and are depicted as dots or bars. Vowels change the way that the associated consonant is pronounced.
