I have found a following sentence in Latin dictionary.
id te Juppiter prohibessit.
Please explain 'prohibessit'.
in the sentence “id te Juppiter prohibessit” that we read in the comedy “Pseudolus “ (The Cheat ),Act 1, Scene 1, line 11, by the Roman playwright of the Old Latin period T. Maccius Plautus (254 BC-184 BC) the verb “prohibessit” is an archaic form of the 3rd person singular, perfect subjunctive active of “prohibeo” whose classical perfect subjunctive active, 3rd.person singular, sounds as “prohibuerit”.
Such an old form “prohibessit” is an Optative Subjunctive which is used just to express a wish.
In fact, “id te Juppiter prohibessit”, where the verb “prohibeo” takes a double accusative, i.e. “id” (=from that) and “te” (= you) , means :”From that may Jupiter preserve you”.
-ID (accusative neuter of the pronoun IS.EA.ID)= from that
-TE (direct object, accusative of the 2nd person pronoun) = you
-IUPPITER (subject, nominative, 3rd declension) =Jupiter
-PROHIBESSIT (3rd sg old perf subj act of PROHIBEO) = may ...preserve.
Note that the perfect subjunctive in a wish is archaic.
