I have been given what I regard as the alarming news that, to be fluent in Arabic, I must be familiar with the verb forms. I have found various sites that attempt to explain the forms, for example: http://arabic.desert-sky.net/g_vforms.html. However, all of the sites have in common that they list the forms for a single verb -- in this case and for some reason in most cases فعل -- but then proceed to explain the forms by reference to completely different verbs. 1. Taking فعل purely as an example, does this mean that this particular verb does not occur in any form but Form 1 ? 2. If it does occur in the other forms, why might its varied meanings not be given ? 3. If it does not occur in the other forms, why can a verb that does seem to occur in the other forms -- خرج or جمع for example -- not be used instead for the explanatory list ? 4. Is there anywhere else where I could find a more helpful explanation of the forms ?
