No links, but here's some copypasta on the internets. (Also, don't whine about it being on the internets and thus lies plox. This guy obviously knows a little bit more about Arabic than most of you.)
Verb stems I and II are spelled identically, and the noun and adjective are also spelled the same as the verbs, though they are all pronounced differently. Arabic verbs distinguish not just tense and person the way English verbs do, but also number and gender. So, a verb has: the first person singular, first person plural, second masculine singular, second masculine dual, second masculine plural, second feminine singular, second feminine dual, second feminine plural, third masculine singular, third masculine dual, third masculine plural, third feminine singular, third feminine dual, third feminine plural; then all of these persons and numbers occur in the perfect, the imperfect the future, the subjunctive, the jussive, the energetic; and the 2nd persons also have masculine, feminine, singular, dual, and plural imperatives; then most of these persons and numbers have forms in the passive voice; so far we’re just talking about stem I...almost all verbs also have all the above forms in several or most of the other ten stems (I, II, III, IV, V, VI, VII, VIII, IX, X, XI); besides all of these, each stem also has masculine, feminine and plural active participles and passive participles, as well as verbal nouns, usually including multiple plural forms; then most of these forms take negative suffixes to form compound negatives; on top of all of this, Arabic verbs also take their direct and indirect objects in the form of enclitic pronouns (for example, كتبتيهولهم, katabtihúlhum = you single female wrote it to them...all one word); on top of all of this, most forms may take a variety of prefixes which correspond to English prepositions and conjunctions, such as "and", "for", "to", "then", as well as prefixed particles that indicate a question or urgency (I’m just thinking of these off the top of my head, so I’m probably overlooking a number of forms); then add to this the freedom with which all of these forms may take diacritics that indicate short vowels, long vowels, doubled consonants, nunation, genitives, accusatives, nominatives, construct-state markers, and definiteness/indefiniteness, plus the fact that words may be lengthened at will for esthetic purposes and to justify text, by adding tashdid in one or more places in a word, without limitation. As example of this, using the previous example: كتبتيهـولهم, كـتـبـتـيـهـولـهـم, كتبتيهولهـــــــم, كتبتــيهـــــــــــولهم, all of which say katabtihúlhum; then add any combination of matres lectionis, such as كَتَبْتِيهُولهُمْ, كَبْتــــيهُولهُمْ, aكتَبتِيهــولهـُم, and so on; and then you may select optional letterforms for esthetic effect, such as ڪَتَبْتِيهُولهُمْ, and so on. I once spent some time trying to figure out how many permutations of a word there could be (but not counting vowel pointing, tashdids, swash characters, or anything like that), but strictly the different grammatical and syntatical forms that are possible, and I stopped counting at 20,000
