"Bony" is often used to describe someone or something that is thin or has visible bones. While it often implies a lack of body fat or muscle, it can also evoke an image of someone who is physically frail or malnourished. In animals, a "bony" appearance can be caused by disease, malnutrition, or genetics. In certain contexts, such as fashion or artistic representation, being "bony" may be seen as a striking feature, especially if paired with other distinguishing attributes like sharp facial features.
Additionally, "bony" may also be used to describe things that have a skeletal or bone-like structure, such as certain foods, plant structures, or even abstract representations of thinness in artwork and design.
