“since” in Latin

Because, forasmuch as, quia: quoniam: quod: cum (subjunctive): quando: quandoquidem; also by qui, quippe qui [SYN. in BECAUSE]. Since these things are so, quae cum ita sint.

From the lime that, e or ex (when an intimate connection is implied): a or ab: post (from, denoting the point of commencement). Since that time, ex eo tempore, or simply ex eo; ex quo tempore, or ex quo (at the beginning of a sentence): since the time when, ex quo (in Liv. and later writers; but cum is the more classical, and should be preferred in writing Latin; e.g., not est annus ex quo, or duo sunt anni ex quibus, but est annus, etc. cum, Krebs).

abhinc (with an accusative when uninterrupted duration is implied; with an ablative, when there is reference merely to the time in or during which a thing is done; the abhinc preceding): sometimes ante with hic. Three years since, abhinc annos tres or tribus annis: six months since, ante hos sex menses: [☞ sometimes the ablative only: paucis bis diebus (a few days ago); and ante is found for abhinc without hic; e.g., qui centum millibus annorum ante occiderunt.] Long since, pridem (opposed to nuper, marking a distant point of time): dudum (opposed to modo, marking a space, but only of some minutes or hours; all often used with jam): he died long since, jam pridem mortuus est: you ought to have been executed long since, ad mortem te duci jam pridem oportebat [☞ not diu, which goes with the perfect definitive: jam diu mortuus est, “he has been long dead”].
