a more intriguing possible origin, however, dates back to 17th century when to have cold feet meant to have no money, probably referring to someone being so poor as to lack shoes.질문이 좀 많은데요..ㅠ

1. to have no money (which was) probably 이렇게 which was 가 생략된 거 맞죠?

2. someone 과 being 사이에도 who were가 생략된거 맞나요?

3. 마지막으로 이 문장에서 as to를 어떻게 해석하는게 좋을까요?ㅠ
