It means that - an idea or feeling which accompany a word and generates a feeling for a person which can be either 'positive or negative'. For example: (1)- The ribbons at her party were really gaudy . Here gaudy means- extravagantly bright . that means above sentence is "Negative Connotation". (2)- He was a prolific composer .
