The aim of this work is to see if the theory that the Romance languages do not stem from Latin can be viewed as a valid scientific hypothesis, or if it falls under the area of pseudoscience.To do that, we will analyse two recent books that present the said theory, comparing them to the three clearest examples of pseudo-linguistic works and with the other one which, being scientific in nature, has been the subject of heated discussions.The conclusion that we aim for is that the hypothesis that the Romance languages do have their origins in Latin, in order to be considered scientific, has to be seen as provisional and can be subjected to falsification, something that both analysed works are trying to do.
