Arabic is a non-concatinative language, it can be described as derivational language meaning that the morphotactics depend rather on affixation i.e. adding morphemes onto the word without changing the radical or the “root", that is, preserving the order of the verb core binyanim, this results in the highly regular inflectional/derivational patterns distinguishing the Arabic language.

It also gives the way to the highly prolific vocabulary that characterizes the Arabic morphology to be reproduced using any suitable production tool carefully designed to work on a root-based algorithm; for example a root like [ksr] "to break" may be seeded into the module to yield roughly 30,000 conjugations which is the thorough listing of the verb paradigm plus all inflectional morphemes applied using specific orthographic and heuristic rules, this is theoretically true for any other triconsonantal sound root with minor exceptions.

Current inflection/derivation tools are limited to the third person masculine singular past tense form which serves as the "dictionary form" used to identify any verb instead of the infinitive the way appears in the English dictionaies for example; this basic form has no but a minor usage in NLP related operations e.g. Tokenization, Stemming or POS tagging not serving as practical. So it is important to generate the "real world" derivational candidates found in ordinary literature texts by having an exhaustive morphological lexicon.
