worries gnawed at her conscience, keeping her awake.

the relentless guilt gnawed at his soul.

the children gnawed on cookies during the long car ride.

the termite colony gnawed away at the wooden post.

the feeling of anxiety gnawed at him throughout the day.

the old tree trunk had been gnawed by squirrels for years.

the rat gnawed a hole in the bag of flour.

the constant criticism gnawed at her confidence.
