Question: Is "He graduated high school acceptable?"
Answer: No. This usage is unacceptable and it grates on my ear. This expression is one of my pet hates. You GRADUATE FROM Harvard University. You will BE GRADUATED FROM Harvard University. But you DO NOT "...graduate Harvard University." That expression sounds as if you are giving the degree to Harvard University and sending Harvard University out into the world to make a living.
Rating of Distractibility: ***. UGH!
