Which word is defined as a strong, abrupt burst of wind?

The term "gust" specifically refers to a strong, sudden burst of wind, typically characterized by a brief but intense increase in wind speed. This definition aligns perfectly with the natural phenomenon of wind behavior, where gusts can occur rapidly and can significantly affect atmospheric conditions and comfort levels outdoors. The short-lived nature of a gust differentiates it from steady winds, emphasizing its abruptness.

In contrast, the other options do not relate to wind or bursts of air. "Haughty" describes a person who is arrogantly superior and disdainful, which has no connection to wind attributes. "Heed" means to pay attention to something, often advice or warnings, and is unrelated to meteorological terms. "Guile" refers to cunningness or deceit in achieving goals, again lacking any relation to the concept of wind. Thus, "gust" is the most fitting term, as it conveys the exact nature of a sudden wind phenomenon.
