Vincent Teo“Can I say,
(i) At / IN the beginning of the race, the hare ran very fast.
9ii) The hare ran very fast At / IN the beginning (of the race)
”
A reasonably good rule of thumb: if of occurs after beginning or end, use at:
At the beginning of the race, at the end of the race
If of is not used, use in:
Everything seemed easy in the beginning. He became happy in the end.
