Latin/Grammar - ne + subjunctive
I would like to know if all the sentences below are correct.
1. Ne timeas.
2. Ne timueris.
3. Ne hoc facias.
4. Ne hoc feceris.
When ne + present or perfect subjuctive is used, its meaning is the same?
all the sentences that you mention are correct, since the negative “ne” + present or perfect subjuctive is used to express prohibition, though “ne” + present subjunctive is common in poetry, while “ne” + perfect subjunctive is common in classic prose.
So, when “ne” + present or perfect subjuctive is used, its meaning is just the same and then both “ Ne timeas” and “Ne timueris“(2nd person singular) mean “Do not fear”, as well as both “ Ne hoc facias” and “Ne hoc feceris” (2nd person singular) mean “Do not do this”.
