AL Mawrid A Modern Arabic-English Dictionary Dr Rohi Baalbaki
This is an Arabic-English Dictionary. It is very helpful if you are trying to learn Arabic but of course the words are not romanized/transliterated so you have to at least know how to read Arabic script and recognise root words.
It is similar to Hans Wehr's but adds the bonus of giving you Arabic Synonyms for most entries.
This Arabic-English dictionary by Rohi Baalbaki should not be confused with the English-Arabic dictionary by Muneer Baalbaki
Authoritative and probably the most popular Arabic dictionary. An indispensable tool for students, researchers and translators.
Unlike conventional Arabic dictionaries, this is arranged alphabetically for ease of use by those not knowing the root letters.
