K -
Words we can rule out based on King clue: Ruler, Princess, Washington?,
Words we can probably rule out based on Mask clue: Football? I think that is probably blue. And it could be international football (like soccer).
Leaves us with....
Stock - international stock - YES
Gold - could be, but reach - MAYBE
Diamond - blood diamonds and shit - YES
Brush - NO
Cat - NO?
File - Again, maybe to like a file that covers international stuff... but a stretch - MAYBE
Point - ***This somehow could be something, I just can't put my finger on it*** - MAYBE
Sock - lol they wear socks in different countries? - NO
Button - International Button Issue is a news term. but a reach - MAYBE
Change - You go through changes as you go from country to country - MAYBE
Mammoth - Because the earth was all one big land mass when they were around? - NO?
Dream - NO?
Church - There are international church groups. Actually a fairly common thing - MAYBE++
Copper - I mean yeah... but also a reach - MAYBE
Earth - We missed this first one out. Earth and international has an obv tie together - YES
South - I mean same as "earth" but more of a reach - MAYBE
So not in order, but imo the categories should be:
YES WORDS - STOCK, DIAMOND, EARTH
MAYBE/YES WORDS - SOUTH, COPPER, CHURCH, GOLD
MAYBE/NO WORDS - CHANGE, BUTTON, POINT, FILE
NO WORDS - DREAM, MAMMOTH, SOCK, CAT, BRUSH
