Arabic nouns and adjectives are declined according to case, state, gender and number. While this is strictly true in Classical Arabic, in colloquial or spoken Arabic, there are a number of simplifications such as loss of certain final vowels and loss of case. A number of derivational processes exist for forming new nouns and adjectives. Adverbs can be formed from adjective
Nouns ( ism) and adjectives in Classical Arabic are declined according to the following properties:
Nouns are normally given in their pausal form. For example, malik "king" would be declined as مَلِكٌ malikun "king (nominative singular indefinite)", اَلْمَلِكُ al-maliku "the king (nominative singular definite)", etc. A feminine noun like malikah "queen" would be declined as مَلِكَةٌ malikatun "queen (nominative singular indefinite)", اَلْمَلِكَةُ al-malikatu "the queen (nominative singular definite)", etc. The citation form with final ـَة -ah reflects the formal pausal pronunciation of this word (i.e. as it would be pronounced at the end of an utterance) — although in practice the h is not usually pronounced, and hence the word may be cited in some sources as malika.
