NotWords: ‘I Graduated’
Now, you hear this all the time: "I graduated high school in 1982."
No matter what year you use in there, the construction is still incorrect. The active verb form of graduate refers to what the school or institution does: It graduates students. Thus you are graduated or were graduated from high school, college, prison ([tag]Paris Hilton[/tag]?) or wherever.
However, this sloppy and misunderstood use of English, "I graduated," has been tacitly recognized as "informal" by dictionary folk, proving once again that, if people use it, the dictionaries will honor it.
