The phrase "haddest out" is an archaic term that means to reveal or disclose something. If we were to use modern synonyms for this term, we could say "brought to light," "uncovered," "exposed," "discovered," or "revealed." Each of these words carries a slightly different connotation, but they all essentially convey the same idea of making something known or revealing it to others. Using more contemporary language can be helpful in ensuring that our communication is clear and easily understood by our audience. So, while "haddest out" may have been a useful phrase in the past, it's best to stick with more current language in our modern era.
