Entertainment / Literature / Connotation: The extra tinge or taint of meaning each word carries beyond the minimal, strict definition found in a dictionary. For instance, the terms civil war, revolution and rebellion have the same denotation, they all refer to an attempt at social or political change. However, civil war carries historical connotations for Americans beyond that of revolution or rebellion. Likewise, revolution is often applied more generally to scientific or theoretical changes, and it does not necessarily connote violence. Rebellion, for many English speakers connotes an improper uprising against a legitimate authority (thus we speak about 'rebellious teenagers' rather than 'revolutionary teenagers'). In the same way, the words house and home both refer to a domicile, but home connotes certain singular emotional qualities and personal possession in a way that house doesn't. I might own four houses I rent to others, but I might call none of these my home, for example. Much of poetry involves the poet using connotative diction that suggests meanings beyond 'what the words simply say.' Contrast with denotation.
