Arabic vocab lists

This site isn't much to look at but has some wonderfully detailed vocabulary lists and grammar lessons: http://arabic.speak7.com

It includes thematic lists, although fairly wide-ranging themes are lumped together: places and sport; food and house; time and weather. They have started to provide alphabetical lists, but so far they have only posted lists for the English letters A-F.

It's not recommended for absolute beginners, or breakthrough (Asset) level, but if you've got a basic vocabulary and are comfortable with reading the script and with how to pronounce words, it could help quickly expand your vocab. Especially if you upload the lists to a flashcard testing tool, or spaced repetition software (SRS).
