What is Meaning Postulates?
Most of student in ELS very confuse about meaning postulate .Meaning postulate is "Unwritten fundamental statements 
 
for example : John Cried Because He Fell
so there are relation between statements 
A = B
C = A
C = B
So if    :    John   Fell     and    John    Creed  so that's only two statements here 
                 C       A                    C           B
and  the  missing in the statements is A=B according to statement  John Cried Because He Fell
The Sentence is all who fell would cry ! ( A=FELL B= CRY) this is meaning postulates but the fundamental statements is false
