What is the difference between denotation and connotation?
Connotation is the emotional and imaginative aspect of something whereas denotation is the textbook meaning of something.
They are not two different things, but rather two aspects of things. When talking about connotation of a subject, it also incorporates the emotions or the implications that come along with the same, however it's denotation will be its simple, basic meaning - almost like a definition.
For example: Tom Robinson was found guilty due to the color of his skin.
Connotation - this sentence shows racial discrimination against colored folk, reflecting to the particular period of time that the novel is set in.
Denotation - Tom Robinson was innocent, however since he was an African American, he was declared guilty.
I hope this helps :D
