Which term relates to the intensity of sensory impressions?

The term "vivid" is closely associated with the intensity of sensory impressions, as it describes something that is strikingly bright, clear, or full of life. When we say that an image or experience is vivid, we emphasize its ability to evoke strong sensations or emotions, making it memorable and impactful. In a sensory context, vivid impressions are those that stand out because of their clarity or intensity, affecting how we perceive and respond to them.

In contrast, while "yearning" denotes a strong desire for something, it does not pertain directly to sensory impressions. "Vigor" refers to strength, energy, or liveliness, which can suggest intensity but is more about physical or mental robustness rather than sensory details. "Witty," on the other hand, relates to cleverness in humor or expression, which does not connect to sensory experiences at all. Therefore, "vivid" is the term that best aligns with describing the potency and clarity of sensory impressions.
