The word "rowdy" describes someone or something that is noisy, rough, or disorderly. It often refers to people, especially in a group setting, who are acting in a boisterous or unruly manner. Imagine a lively party where people are laughing loudly, playing games, and creating a lot of commotion—that's what rowdy behavior looks like.
The word "rowdy" is believed to have originated in the 19th century from a Scottish dialect word "rowdie," meaning "noisy, uproarious." Its roots may be traced back to the Scots word "roudy," which further connects to the action of causing a stir or commotion.
