I hope not. Some people make or commit blunders. Politicians sometimes make blunders, and therefore they are “blunderers”.
A blunderer (metepatas) is a person who makes serious mistakes, usually because the person is unthinking (irreflexivo) and careless (descuidado).
It is also a verb – to blunder. In Spanish you might say that the person “comete unos graves errores” or it could be someone who makes a stupid mistake, “una person que comete un error garrafal”.
- Mr. Corbyn, the Labour Leader in the UK, made another blunder when he failed to stop the Labour Party´s abusive (insultante) behaviour towards Jews.
- My biggest blunder in the exam was to leave a question unanswered (mi major metedura de pata en el examen fue dejar una pregunta en blanco).
- Stop blundering about! To “blunder about” is to move about in clumsy (torpe, patoso) way.
- Mr. Trump “blundered into” a meeting, meaning that he entered in a clumsy and noisy way.
- Mr. Putin blundered around in the dark (…andaba dando tumbos el la oscuridad).
- What a blunder! In other words, what a big and careless mistake.
So do not make blunders and do not blunder into meetings, and therefore you will not be a blunderer.
