Most cornerways is an uncommon term, and it can be challenging to find synonyms for it. However, there are several words you can use that mean nearly the same thing. For example, you can use the word "diagonal" to replace most cornerways. The term diagonal refers to something that goes or runs across from one corner to another in a slanted or oblique direction. Another option is to use the word "oblique," which means taking a slanting or sloping direction. For a more precise term, you can use "cater-corner," which means positioned diagonally opposite to or across from each other. Alternatively, you can use "crooked" or "angled" to take the place of most cornerways.
