Am I correct in thinking that "at the beginning" should be followed by "of something" and "in the beginning" shouldn't?
Example:
1. At the beginning of the lesson I was sleepy.
2. In the beginning everything looked simple.
You may well have been told this, and the OALD seems to suggest it, but the figures tell us that it is far from an absolute rule.
COCA has 7,448 citations for 'at the beginning', 5,224 of them being for 'at the beginning of'.
It has 3,295 citations for 'in the beginning', 526 of them being for 'in the beginning of'.
