There seems to be some ambiguity between the connotation and definition of a word / word group / phrase.
The dictionary entry seems to be that a definition is more of a primary description of a word whereas connotation seems to be more of an alternative meaning or implication.
Further, despite the dictionary entry, I feel like I hear them used synonymously both on this site and in "real life."
So, long question short, what constitutes a definition and what constitutes a connotation?
