I’m currently on chapter 14, and here are some forms that I have problems with in various chapters so far, and I’d like to have your educated opinion:
Sequent> e > nocte, Crūsōeus sēcūrus recumbēbat
The present participle “sequente” is a little out of place, the adjective “sequentī” would be much more appropriate in this context. It’s not just the night that happens to follow, but the night that naturally follows.
Jam vērō sitī exārsit vehementissimā, > cui explendae > cum idōnea nōn esset aqua putrēdine corrupta, opportūnē mālōrum citreōrum meminit.
Nowhere I find explēre with the dative with this meaning, only the genitive.
Tum ille territus > undique > circumspicit ; audītō vel levissimō foliōrum strepitū stupet,
Undique is weird here. The intended meaning is “he looks everywhere around [from where he is]”, but “undique” makes it “he looks from everywhere around”. I think it’s a bad word choice.
Tandem collēctīs vīribus fugam corripit, quasi īnstārent > ā tergō> , neque prae terrōre respicere ausus est.
Here, “ā tergō” is used for the position, “behind him”. It looks like “tergum” is normally used only for the physical back of something/someone, not the position. Indeed, we have “ā” before, which may give some “from his back” meaning, but I’m still not quite confident about this one, and I don’t find “īnstāre” with ā+abl. Is this really meaningful?
