Okay so there is a porch and it is say 20 feet wide. In the middle is a set three steps leading to the porch. So you go from the ground up one step, two steps, three steps, and then step to the porch.
Is that four steps or three steps?
If you have "over three steps" you need a handrail.
Honestly, I'd rather have a rail around the entire porch- but, as I said in the title, I am being pedantic and am curious about how this should be interpreted.
Each time you lift a foot is a step, so three steps and the top landing is four total. Think of it another way. If you took away all three steps, how many steps up would it be - one!
Again- pedantic- mostly for fun.
I would say that you are using step as a verb not a noun. So lets say the steps are gone it is a house with a porch. I must install some steps so people can get in the house. How many steps do I install? Three.
