Connotation
A connotation is a commonly understood cultural or emotional association that some word or phrase carries, in addition to the word's or phrase's explicit or literal meaning, which is its denotation.
A connotation is frequently described as either positive or negative, with regards to its pleasing or displeasing emotional connection. For example, a stubborn person may be described as being either strong-willed or pig-headed; although these have the same literal meaning (stubborn), strong-willed connotes admiration for the level of someone's will (a positive connotation), while pig-headed connotes frustration in dealing with someone (a negative connotation).
Usage
"Connotation" branches into a mixture of different meanings. These could include the contrast of a word or phrase with its primary, literal meaning (known as a denotation), with what that word or phrase specifically denotes. The connotation essentially relates to how anything may be associated with a word or phrase, for example, an implied value judgment or feelings.
