Sentence 9 reads:
Post bellum multos libros de pace et remediis belli videbant.
After the war, we were seeing many books of peace and remedies of/for the war.
I wondered why ‘Post bellum’ is not written as ‘Post bello’ (Ablative) because this is an adverb phrase telling time of action. The book wrote it as the Accusative but this is not an object being acted upon.
Could someone explain the difference between ‘te’ and ‘tu’?
Could someone explain the difference between ‘te’ and ‘tu’?
I’m not familiar with the Wheelock textbook, so I could potentially be telling you how to suck eggs, but tu is nominative, used for the subject of the sentence. Te is the accusative and ablative form of tu. So use it after prepositons and as the object of the sentence, among other things.
Post bellum multos libros de pace et remediis belli videbant.
As far as I understand post here is acting as a preposition. Most prepositions (I can think of only eight common exceptions) take the accusative case, which is not, I should add, solely used for the something being acted on.
“Time when” can be expressed by the ablative, for example -
Autumno folia rubra videmus
Here “autumno” is in the ablative case and means during autumn. So you’re not entirely incorrect. I believe “during”, when not used with a time phrase, would be translated as per or inter together with the accusative case. Similarly, ante takes the accusative as well.
