verdadero
/beɾdaˈdeɾo/ · A2 · adj
true, real
verdad (truth) + -ero: the truth-y one, from Latin veritas like verify
Verdad means truth, from Latin veritas, the same root as English verify, verdict and veracity. The ending -ero turns it into an adjective: having truth. So verdadero is literally truth-ful, covering true, real and honest.
