One might also note the different spellings for the plural of storey.
Both stories and storeys exist in English.
I prefer storeys to avoid confusion with the plural of story.
And the different spellings for "storey" (BE) / "story" (AE) when referring to floors of a building.
I think the way the stor(e)ys are counted is the same, just the way they are named is different.One might note the different ways of counting storeys in US, England, and Europe.
