A distinction without a difference is an informal fallacy where an author or speaker attempts to describe a distinction between two things where no discernible difference exists. It is particularly used when a word or phrase has connotations associated with it that one party to an argument prefers to avoid.
For example, a person might say "I did not lie; I merely stretched the truth a little bit."
Form of the fallacy Claim X is made where the truth of the claim requires a distinct difference between A and B. There is no distinct difference between A and B. Therefore, claim X is incorrectly claimed to be true.
Example In the following conversation: Sergio: There is no way I would ever even consider taking dancing lessons. Kitty: How about I ask my friend from work to teach you? Sergio: If you know someone who is willing to teach me how to dance, then I am willing to learn, sure. Sergio's fallacy is thinking that being taught by someone is different from taking a lesson.
