Dear VR ji,
I am really enjoying myself by self studying Arabic.
I find my prior knowledge of Sanskrit really helpful becos even Arabic has somewhat Sandhi like rules for certain letters.
Letters are divided into Sun(Solar)letters and Moon(Lunar) letters.
There are changes akin to Sandhi like changes when dealing with the letter AL when it is proceeded by Sun letters.
Sun letters remind me of Soft consonants in Sanskrit where Sandhi changes are seen.
Moon letters remind me of Hard consonants in Sanskrit when some letters remain unchanged.
There is also the concept of Dual in demonstrative and personal pronouns in Arabic...making it all easy to understand cos Sanskrit too has the same.
So its so so nice to be seeing similarities in both these languages and the script is just simply beautiful..its romantically cursive.
