The word 大家 is formed through the conceptual combination of its two component characters: 大 (dà), meaning "big" or "great", and 家 (jiā), meaning "household", "family", or "home". By merging these ideas, it visually and semantically constructs the notion of a "big family" or "great household", which then extends metaphorically to represent a collective whole, meaning "everyone" or "the public". Its formation is essentially a direct and intuitive pictorial-semantic blend, where the whole meaning emerges from the combined imagery of its parts.
