Question: Is there a difference between "shined" and "shone"?
Answer: "Shine," "shined," "shone": Use "shined" with a direct object: "He shined the flashlight on the house." "Flashlight" is the direct object of "shined." Shined what? "Flashlight."
Without the direct object, use "shone": "The sun shone only once this week." Thanks to the NYT Manual of Style and Usage.
Rating of distractibility: (***). I didn't know the distinction! But the "sun shined" would not sound right. Nor would, "He shone the flashlight." On the basis of sound alone, I think many people would be distracted. I learned something writing this blog. RayS.
