Merhabn
Hello friends, I found this dictionary on the web by chance and liked to introduce it to you. I wish you'll be able to use it, since the real Arabic dictionaries depend on the root of the word (either verb or noun), by removing all the addiditive letters which are gathered in (سألتمونيها).

The dictionary's name is مختار الصحاح Mokhtar Al-Sehah
And Here you'll find it.

I hope it'll be useful for you all.
Best for All
