Hi folks,
I've been trying to work out a set of rules that could explain the choice of prepositions with 'covered':
covered with / covered by / covered in.
None of the dictionaries that I looked in give any reasonable interpretation.
So I haven't been able to crack this puzzle so far. All I can say is that 'with' is by far the most frequently used one, and 'in' often occurs when cover stuff is undesirable and should be removed, e.g. He was all covered in blood, snow, etc.
Sometimes it seems the three of them are possible in the same context, e.g. The trees were covered with / by / in snow.
I wonder if you could suggest contexts which would accept only one of the options, excluding the others.
Let's have a discussion. The problem seems to be really challenging.
