Wrecker → The word originates from the Old English 'wrecan' (meaning to drive out or to punish) and the suffix '-er' (meaning a person who). A wrecker is a person who drives out or punishes, often associated with the act of demolishing or destroying something.
Think of someone who 'drives out' ('wrecan') or 'punishes' — that's why a wrecker is someone who causes destruction.
