Well, take 'pop'. There was a balloon seller in a carnival. He had balloons of all colors. One day, a little girl came to his stand and accidentally popped one of the balloons with her finger. Instead of getting angry, the balloon seller laughed and told her a story about how popping balloons can sometimes be a sign of celebration. In some parties, people pop confetti - filled balloons for fun. So, the 'pop' in the 'op' word family can have different meanings depending on the context.
