The word "怀里" is formed as a compound noun through the combination of the character "怀", which means "bosom" or "to cherish", and the character "里", which means "inside" or "interior". Together, they create a spatial concept where "里" specifies the locative relationship, literally meaning "inside the bosom" or "within the embrace", to denote a physical or metaphorical place of closeness, safety, or intimacy, such as holding something or someone in one's arms.
