The Dictionary of Modern Written Arabic by Hans Wehr is widely regarded
as the foremost Arabic-English bilingual or translation dictionary and
has particular usefulness for students of Modern Standard Arabic. The
morphology and syntax of written Arabic is essentially the same in all
Arabic countries. Unlike many other Arabic-English dictionaries, it
arranges each Arabic word according to its consonantal root. Foreign
words are listed in straight alphabetical order by first letter (in the
Arabic script). Arabicized loanwords, if they can clearly fit under some
root, are entered both ways, often with the root entry giving reference
to the alphabetical listing.
