This rock has been here for hundreds of years.

He is always a reliable person.

He is my reliance.

He owns a big house.

He was sitting on a rock, looking out at the sea.

Iwao is strong like a big rock, and you can rely on him.

He chose that method against his will.

This tree is very hard.

He is a person with a strong heart.

He finished the job in slightly more than an hour.
