Oooh, alright, it'd be a different approach then. I'm more fluent in pure Javascript than Perchance syntax, so I may miss a thing or two here and there :B

Anyway, I think this would be the pattern you want:

AdjectiveNoun()=>
  let combo=[];
  for(const a of Adjective.selectAll) {
    for(const n of Noun.selectAll) {
      combo.push([a,n].join(' '));
    };
  };
  return combo;

Which translates to "for each adjective, give me that adjective plus each noun". That's the generic way to get all variations. It's quite possible that there is simpler way to do it in Perchance that I'm not aware of though.

That aside, the join-lists-plugin works for turning an array into a list, far as I tested:

output
  [t=Thing] [t]

Thing=[joinLists(AdjectiveNoun()).consumableList]

OK, now the entire generator (in case having each piece separately is too confusing)

joinLists = {import:join-lists-plugin}
title
  tee--temp

output
  [t=Thing] [t]

Thing=[joinLists(AdjectiveNoun()).consumableList]
AdjectiveNoun()=>
  let combo=[];
  for(const a of Adjective.selectAll) {
    for(const n of Noun.selectAll) {
      combo.push([a,n].join(' '));
    };
  };
  return combo;

Adjective
  furry
  spiky
  green
  loud
Noun
  rat
  bug
  cat
  tree

Hope I'm not getting it wrong again haha :DD

Alright, happy coding!
