The word "大肉" is formed by directly combining the character "大" (meaning "big" or "large") with "肉" (meaning "meat"), where "大" modifies "肉" to specify a type of meat that is considered substantial or primary, often concretely referring to pork in common usage. This structure creates a compound noun through a simple adjective-noun relationship, conveying a specific culinary reference without additional morphological processes.
