Abstract:

The Arabic language has several characteristics that increase its strength and capacity, such as synonymousness, derivation, polysemy, antonymy, syntax and other characteristics. Among these words are prepositions, which are frequently used in The Arabs speech, so the grammarians paid attention to their books. They have narrated its utterances including what were agreed upon and what were disagreed. Some of them were very keen to study them in details and some were concise However, they studied it in terms of the alternation, which is that a letter is used to give the meaning of another letter. They discussed this term in details and varied from grammarians who deny alternation completely, others said it is possible to be used and others said it should be used and everyone presented his evidences, proofs and examples about this term. Their sayings are documented in many of the Books of Arab Heritage. Ibn Malik al-Andalusi was one of those grammarians who supported those who said that “alternation “should be used and studied it in detail and gathered evidence and proofs to support his opinion more than anyone else. He was pioneered in that hearing of the words of Arabic poetry and prose. His attitude on inference to Hadith has contributed to increasing his audio evidence and consequently, he promoted “alternation” between letters putting it in a distinctive place so other grammarians followed him later.
