I came across a sentence which had かぶらず. As, per the picture, the meaning is nothing to wear on head. However, I was trying to figure out whether かぶらず is part of conjugation of the verb かぶる, however, many websites were not showing such conjugation, and the meaning of word かぶらず for that matter. Thereafter, I googled it and found it meant not wearing.
my question is; whether is かぶらず is the conjugation of かぶる or is it something else?
Is it some sort of a negative form to be used with particle も which also has the function of showing nothingness?
Secondly, I just wanted to seek clarification on usage of particle に, are we using this particle and not が, because if we use that particle it would me, my head has nothing to wear, which can also be misunderstood as, my head, literally has nothing to wear, which would be different from there is nothing to put on my head, which the author is trying to show.
