Every normal child who is exposed to linguistic input in an interactional      
environment acquires the complex structure of the language at a very early age, 
in a very short time and without any explicit training. This fascinating 
character of language acquisition  lead many researchers to study on the 
aspects of language acquisition.  The present study  is on the morphological 
analysis of Turkish and on learning the morphophonology of   Turkish       
by using the non-monotonic setting of Inductive Logic Programming, ILP.    
A model for the acquisition of morphophonology by children is proposed   
and is implemented in a computational system. Assuming that grammar is composed 
of the lexicon, the phonological representation and the semantic  
representation which are connected to the central structure, i.e. surface  
grammar, we aim at generating a part of the central structure, namely  
the morphophonology, when phonological, semantic and lexical knowledge   
are given.
