howler

The word 'howler' is a straightforward agent noun formation from the verb 'howl'. The verb 'howl' itself is an ancient onomatopoeic word from Old English, imitating the sound of a prolonged, loud cry, often associated with wolves or the wind. By adding the agent suffix '-er', the word originally denoted something that howls, such as an animal. In the late 19th century, the term developed a figurative sense in British slang, applying the concept of a loud, jarring noise to a glaring and ridiculous error in speech or writing, one so obvious it seems to 'cry out' for attention. This semantic shift connects the primitive sound to a modern social blunder.
