An accident is something tragical and on a bigger scale but something accidental is when we trip or something like that
A park is a place where we can relax and a car park is a place where we leave our cars temporarily
A site is a place like a plain but a sight is something like ,,The library is in my sight’’
A road sign is an object that gives the driver indication like the speed limit but a roadside is where pedestrians walk
Poring is when you are absorbed in reading or studying but pouring is when flowing rapidly in a steady stream
A campsite is a place used for camping a camper van is a large vehicle with living accommodations
I hope I helped you
