Within the broad framework of syntactic and semantic codes, the addresser will select signifiers that, in the particular context, will best represent his or her values and purposes.

So the addresser must attempt to compensate for the known problems when constructing the final version of the message and hope that the preferred meanings will be identified when the message is received.
