Definition of the word bluster

The word "bluster" has its roots in Old English and Middle English. The term originally referred to a type of wind or storm that was harsh and turbulent. By the 14th century, "bluster" expanded to mean to breathe or blow strongly, like a strong gust of wind. In the 16th century, the meaning shifted to describe someone who spoke or behaved in a loud, boastful, or aggressive manner, much like the turbulence of the original wind. This sense of bluster as loud and boastful speech was likely influenced by the idea of a stormy wind making a loud and intimidating noise. Today, "bluster" is commonly used to describe someone who talks or behaves in a loud, arrogant, or aggressive way, often without substance or backing their claims.
