What word describes a strong, penetrating scent filling a space?

The word that best describes a strong, penetrating scent filling a space is "permeated." This term conveys the idea of something spreading throughout an area, particularly in relation to scents or smells. When a fragrance permeates a space, it suggests that the scent is not only present but also deeply infused into the environment, making it evident and robust throughout.

In contrast, the other words do not convey the same meaning. "Evaporated" refers to a liquid turning into vapor and does not apply to the presence of a scent. "Faded" indicates a decrease in intensity or disappearance, which contradicts the idea of a strong scent. Lastly, "cleared" implies removing something or making an area empty, which again does not align with the concept of a scent filling a space. Therefore, "permeated" accurately captures the essence of a potent aroma saturating an environment.
