The term "boneless" refers to something that is without bones or skeletal structure. This can be used in a literal sense, such as describing an animal with no bones (e.g., fish) or referring to a part of the body that has lost its bone structure due to injury or disease (e.g., "He broke his arm and now it's boneless"). In a figurative sense, "boneless" can be used to describe something that lacks strength, courage, or determination - for example, someone might say of another person, "he's just a boneless wonder."
