In British English, the word “bully” primarily refers to someone who intimidates, harasses, or mistreats others, often in a repeated or aggressive manner. This definition aligns with its use in many English-speaking countries. Bullies are typically associated with schools, workplaces, or social situations where they exploit power imbalances to control or harm others, whether physically, verbally, or emotionally.
Historically, however, “bully” had a more positive meaning, derived from the Dutch word “boel”, meaning “lover” or “friend.” In the 16th century, it was used to describe someone as excellent or admirable. For example, the phrase “bully for you” remains a sarcastic or enthusiastic expression, meaning “good for you.”
Today, the negative connotation is most common in British usage.
