6.8 beginning of clause for emphasis
You can emphasize the adjunct by placing it at the beginning of the clause, in front of the subject.
The adjunct is often separated by a comma from the rest of the clause.
This position is often used in written stories to draw attention to the adjunct. For more information, see paragraph 10.93.
Note that adverbs of degree are rarely used at the beginning of a clause: see paragraph 6.45.
