everyone. I always think there are two types of 3rd conditional. One is use to express counterfactual situation in the past e.g.
He would have spurred the pony, but his father made them dismount beside the bridge and approach on foot.
But there is another type of 3rd conditional, which looks quite like the first type, used to show complete imagination of situation in the past.
e.g Robert Baratheon and his brothers were all big men, as was the Hound, and back at Winterfell there was a simpleminded stableboy named Hodor who dwarfed them all, but the knight they called the Mountain That Rides would have towered over Hodor.
So how do you differentiate these two type of 3rd conditional? Please let me know your opinions. Thank you for your help.
