Correct use: Allways, always or all ways
The two correct words out of this list are: “always” and “all ways”. “Allways” is just a common mistake. However, the other two have different meanings.
Always is a synonym for “all the time”, while “all ways” refers to the number of possible solutions. “All ways” is often used with an article or an adjective: “all the ways”, “all your ways”.
I’ve always thought about this, but I never took any actions.
This problem can come around all ways (both ways, both sides).
