How it's used

隧 is a bound morpheme that almost exclusively appears in the compound 隧道. It is rarely used on its own in modern spoken Cantonese, as speakers prefer the full two-character term to refer to any underground or underwater passage. While it can technically refer to a pedestrian subway, it is far more commonly associated with vehicular tunnels in Hong Kong.

Measure word

tiu4tìuh

Examples

The car just passed through the tunnel.

Common phrases

cross-harbour tunnel

Common mistake

Learners often confuse 隧道 with 地鐵, but 隧道 refers specifically to the physical structure of the tunnel itself, whereas 地鐵 refers to the subway train system.
