I like the flatness of this table.

This table is very flat.

Taira is my best friend.

This country has entered a peaceful era.

He is using a bilingual book to learn English.

He fell into self-loathing.

He leaned against the wall because he was tired.

He leaned against the wall to rest his fatigue.

He can play the xylophone well.

He is wearing an expensive suit to show off his air of importance.
