When we are talking about some book or movie it's very common to see the following statements:

  • "Esse filme é baseado em fatos reais.";
  • "O livro foi feito com base em fatos verídicos.";

My question is: Is it redundant?

I already saw some arguments saying that a "fato"(fact) is always real, but I think that we can use "fato fictício" or something, so "fatos reais" is not redundant to me.

Am I wrong?

    Note: "fato" is pt_BR and "facto" is pt_PT.

  • There are also fatos surreais. Is this a pleonasmo? Repetitions are frequently used to highlight a specific idea in several languages (real fact vs true facts.

  • @JorgeB. Hasn't the O.A. done away with the "c" in "facto"?

  • @Centaurus no, because fato is a suit on pt_PT: Com o Acordo Ortográfico, escreve-se facto ou fato?

Although there may be some redundancy, depending on how you define "fatos", "baseado em fatos reais" is a set phrase and means the same as "baseado em fatos verídicos". It's current usage and nobody stops to think whether it's redundant or not.


It depends on the meaning you are using for fa(c)to:

fac·to |ct|

(latim factum, -i, aquilo que se fez, façanha, proeza, acto) substantivo masculino

  1. Coisa realizada. = ACTO, FEITO

  2. Acontecimento.

  3. Sucesso.

  4. Assunto (de que se trata).

  5. Lance.

"facto", in Dicionário Priberam da Língua Portuguesa [em linha], 2008-2013, http://www.priberam.pt/dlpo/facto [consultado em 08-01-2016].

If you add real to those definitions, only the first turns to look redundant: coisa realizada real.
