I came across the following sentence in a book:
and searched on Jisho.org for 障もなく. It sent me to https://jisho.org/search/障む, saying that "障もなく is the negative form" of 障む。
However, I know that for that to be correct, it would have to be まなくて, not what is written in the book. Then I remembered that the も could be from the volitional form; and looked through my Genki 2 textbook, but failed to find the conjugation for negative volitional phrases, which means that 障もなく is either not volitional, not negative, or I'm leaping down another dead-end rabbit hole again via wrong analysis of what the text means.
