The heat inside the closed car became unbearable within minutes.

The unbearableness of the heat made evening walks impossible.

The summer heat was unbearably oppressive, forcing everyone indoors.

Please unbear the horse's bearing rein before the competition.

The relentless heat was unbearing the hikers, forcing them to seek shade.

The unbearing pear tree stood silent through the summer, frustrating the orchard keeper.

He unbears the heavy crate from the truck, making the job easier for everyone.

The unbearability of the silent, unlit hospital corridor made her hurry through it with trembling hands.
