word meaning of con
Usage notes [edit]. con-is a prefix added to many words to give a sense of with or together. The o is long before s and f, whence cÅnspÄ«rÅ and cÅnferÅ. Before b, p, and m, the n assimilates to m (whence com-). Other forms are co- , col- (used before l), and cor- (used before r).
