How it's used
This idiom is primarily used in descriptive or literary contexts to emphasize a sense of immense scale. While it functions as an adjective, it often requires the particle 嘅 when modifying a noun, such as 一望無際嘅天空. It carries a slightly more formal or poetic tone compared to everyday conversational descriptors like 好大.
Examples
It is boundless here, my mood feels better too.
Can you see that vast expanse of grassland?

Common mistake
Avoid using this to describe indoor spaces or small areas, as it specifically implies a horizon or an expanse that exceeds human visual range. It is strictly reserved for large, open outdoor environments like oceans, deserts, or plains.
