Etymology
The word 'bluster' emerged in the late Middle English period, likely as an onomatopoeic formation meant to imitate the sound of a gusty wind or waves. It is related to Low German and Dutch words like blustern and blutsen, which carry similar senses of blowing violently or swelling proudly. This direct sensory link to noisy, forceful natural phenomena provided the perfect metaphorical foundation for describing loud, boastful, or threatening human speech that is ultimately as insubstantial as a passing gust. Thus, the word's evolution captures a vivid transfer from the literal realm of weather to the figurative domain of human behavior.
Analysis
The word 'bluster' is a simplex word of likely imitative origin, formed to mimic the sound and force of a gust of wind or loud, empty speech. Its functional role is as a complete lexical unit.
