The first app (Android/iOS) that really knows how to conjugate Arabic verbs

The Arabic verb system is very logical, however, there are exceptions as in any language. The conjugation rules are based on 14 major conjugation patterns with 182 subtypes. Since the underlying system is totally different from English, beginners often struggle to conjugate verbs.

Now, there is help.  A great app called CAVE  (مَغارَة), available for Android and iOS.

A programmer and Arabic expert, Graeme Andrews (who by the way has written a great tool for Lane’s dictionary) told me about the app.

The CJKI Arabic Verb Conjugator (CAVE) can be used to conjugate almost every Arabic verb in all tenses and moods.

  • 1,700 Arabic verbs are fully conjugated
  • English translations for all Arabic inflected forms
  • romanized transliteration to indicate the word stress
  • pronounced audio for each of the inflected forms (410,000 items!)
  • search for verbs in Arabic, transliterated form or English
  • user-friendly interface


Here is how the app looks like:

It is available for Android and iOS.


Who should use the app?

The author writes on his website: “As the learner is increasingly exposed to Arabic using CAVE as a learning aid, he or she gradually internalizes the rules by osmosis, rather than through a conscious process of rote memorization. Eventually, producing the correct form becomes an automatic, mostly unconscious, process”.

I still believe that memorizing verbs helps a lot, especially if you want to speak fluently. But, as the author puts it, “CAVE puts at the user’s fingertips a wealth of detailed information on every aspect of Arabic verb conjugation.”
