How can I reduce this sentence? Does one of these work?
A. The snow falling overnight has caused traffic chaos.
B. The snow, falling overnight, has caused traffic chaos.
C. The snow having fallen overnight has caused traffic chaos.
D. The snow, having fallen overnight, has caused traffic chaos.
E. Falling overnight, the snow has caused traffic chaos.
F. Having fallen overnight, the snow has caused traffic chaos.
It's Friday evening so without racking my brain too much, I'd say that we reduce "ing" clauses and some passive clauses, but, [subject to correction of course], not past tense clauses.
What about? Overnight snowfall caused traffic chaos.
As you omit the relative pronoun and the part of the verb that agrees with the subject, I would go for
'The snow falling overnight caused traffic chaos'
Riverkid, as far as I know all relative clauses can be reduced as long as the relative pronoun is the subject of the verb, but it is not always a good idea.
Try reducing this...
'The man who built the house is dead.'
