Look at this example: For the butler to attack the robber would be surprising.
Here, the butler and the robber are assigned accusative Case. Is 'For' assigning case to the butler and 'to attack' assigning Case to the robber? Doesn't there need to be a subject in the clause, so something with nominative case?
Am I right in saying 'to attack' does not assign nominative Case to anything?
For sentences such as: 'That the butler attacked the robber is surprising.' I understand the Case assigning, attacked assigns nom. to the butler and acc. to the robber. As soon as an infinitval clause gets involved, I find myself getting very confused. Can anyone help?
