There are a few theories about its specific origin:
* "Boele" or "Boel": These Dutch words mean "brother" or "friend," which might suggest a more playful or camaraderie-based meaning in earlier usage. Over time, this could have evolved into a term for someone who used their dominance within a group to intimidate others.
* "Bull": The Dutch word for "bull" was "bulle," and this may have contributed to the association of the word "bully" with physical strength and intimidation.
* "Builen": This Dutch word means "to swell," which could be a metaphorical reference to a bully's puffed-up chest or ego.
It's important to note that the word "bully" has been used in various ways throughout history. It was originally more of a neutral term, sometimes even meaning "lover" or "sweetheart." However, it gradually became associated with aggressive and intimidating behavior, especially in school settings.
