Etymology Origin:
The word "bluster" originated in the late Middle English period, borrowed from Middle Low German blüsteren, which described the sound of wind or stormy noise. Over time, it evolved metaphorically to describe loud, empty speech or bullying behavior—much like the noisy but powerless force of wind. The suffix "-er" reinforces the idea of an agent (e.g., a "blusterer" is one who blusters).
