Usage Notes
Big is the most common, informal way to express largeness. It's versatile across registers but less formal than 'large' or 'substantial.' Often used for emphasis ('big problem,' 'big day'). In business contexts, implies importance ('big decision'). Common error: overusing in formal writing where 'significant' or 'substantial' would be more appropriate. Works well in casual speech and accessible writing.
