Question

He's walking at / to the station

Answer 1

He's walking to the station

Answer 2

"He's walking at/to the station" means that someone is currently walking either at or towards the station.

If we say "He's walking at the station," it suggests that the person is already at the station and is currently walking around within the station premises. They may be walking on the platform, in the waiting area, or exploring the different sections of the station.

On the other hand, if we say "He's walking to the station," it means that the person is currently on their way towards the station. They are walking with the intention of reaching or arriving at the station. They may be walking on the sidewalk, crossing streets, or following a specific route to get to the station.

The choice between "at" and "to" depends on the context and the specific situation being described.
