Category:Arabic verbs with unknown or uncertain active participles

Arabic verbs where the active participle is unknown or uncertain.

For Classical Arabic, this happens with the verbal noun of form-I verbs and the active participle of form-I stative verbs (those whose past vowel is i or u). For these verbs there is no single consistent pattern for the form in question, and thus it needs to be specified explicitly. If not done so, it shows up as a question mark and the verb is placed in this category.
