IPA: /ˈmɔːlər/
KK: /ˈmɔːlər/
A person or animal that attacks and injures someone or something, often in a violent way.
The bear is known as a fierce mauler in the wild.
Mauler → The word 'mauler' originates from the verb 'maul' (from Middle English *maule*, meaning to handle roughly or to beat). The suffix '-er' (meaning a person who) indicates someone who mauls. Thus, a mauler is a person who handles or attacks someone or something roughly or violently.
Think of someone who 'handles roughly' ('maul') and the '-er' means a person. A mauler is someone who attacks or treats something in a rough manner.
