This is a special day.

He cooked specially for me.

He is doing special exercises to strengthen his dorsal interosseus muscle.

The palmar interosseus muscle is a part of the hand muscles and supports the movement of the fingers.

The plantar interosseus muscle is a part of the foot muscles and controls the movement of the toes.

He fractured his carpal bone.

During summer vacation, I will go to the beach.

While he was taking a nap, I finished my homework.

He took a little pause before speaking.

There is a deep bond between him and me.
