Are both interchangable?
Which ones are from British English? Which ones are from American English?
Answered by Reed
They are interchangeable. I think backward, inward, westward, etc., are more proper. Adding the "s" on the end is more colloquial, but by common usage, is quite acceptable. I don't know which is more American or British.
