He unsparred his opponent with a powerful punch.

He was unsparing in his criticism of the government.

The hurricane left no building unspared.

The artist unspars the colors on the canvas.

He is unsparring with his opponent in the boxing ring.

He unsparred the sails and prepared the boat for the storm.

The time we have with loved ones is unspareable.

He is unspare with his time when it comes to helping others.

Her love for him was unsparable.
