Sort:  

Probably I often do mistakes of spelling where "a" or "e" is expected in some wording. Good to understand the difference of such terms nevertheless.

EN-US is what I use generally, but I still use these EN-UK words in my writing:

  • Grey;
  • Inquiry;
  • Towards (and Toward, so 50-50 for that one).

Mainly I use "-er" instead of "-re" except for one word: lightsabre.
