Writing arabic can be fun and easy once you learn to recognize the different shapes that an alphabet can appear as. 22 of the 28 Arabic letters have 4 variants:
1. Standing alone.
2. As the first letter in a word.
3. Inside the word, between two other letters.
4. As the last letter in a word, joining to the letter in front.
As for the remaining 6, they never join to the succeeding letter, even when they are inside a word. This means that the writer has to lift his pencil, and even if he is inside the same word. The following letter will have to be written as if it was the first in a word. Examples of these odd 6, see 'alif and wâw. The following lists each alphabet and its possible forms:
h (hā') stressed h- always transliterated in bold
s (sād) stressed s, always transliterated as bold s
d (dād) stressed d, always transliterated as bold d
t (tā') stressed t, always transliterated as bold t
z (zā') stressed z, always transliterated as bold z
