Original text - Latin - Nil tam difficile est, quin quaerendo investigari...

Nil? Shouldn't it be Nihil?

"Nil" ( ) is a shorter form for "nihil", Alex.

Anyway "possiet" is not correct in Latin. It should be "possit" for sure.

Maddie, could you correct your source text?
Then I can build an English bridge for it.

Yes, but I believe that only a bunch of authors use "nil" instead of "nihil"... Anyway OK, dear Aneta
