The adjective "chunky" is typically used to describe something that is large, thick or substantial in size and shape. It can be applied to a wide range of objects, from clothing items such as sweaters or knitwear, to food products like peanut butter or granola bars. In terms of physical appearance, "chunky" often implies a sense of robustness, heftiness or substantiality - something that is not delicate or fine-looking, but rather solid and substantial in its construction.
