Tautology
A tautology is an expression or phrase that says the same thing twice, just differently. It is usually unwelcome because it makes you sound wordier than you want. But, sometimes, tautology can help to add emphasis or clarity or introduce intentional ambiguity.
There are two definitions of tautology: verbal and logical.
Verbal tautology involves just a few words that mean the same thing and the second one doesn't add any new information.
Logical tautology is valid in all situations [YourDictionary].
Tautology is using two words or phrases that express the same meaning in a way that is unnecessary and usually unintentional [Cambridge Online Dictionary].
Tautology includes unnecessary words, such as the repeatedly used phrase [Quinn, p. 411].
The word tautology originates from the Greek word tautologous – ‘repeating what is said.’ ‘A cyclist traveling on a bicycle’ is a tautology because a cyclist, by definition, is someone who rides a bicycle [Vocabulary.com].
