ὁπότε
of Time, correlat. to πότε, much like ὅτε:
I. with the ind., "when", Lat. quando, Hom.: —εἰς ὁπότε, with fut., "when, by what time", λέγειν εἰς ὁπότ᾽ ἔσται Aeschin.
2. with the opt. in reference to the past, "whenever", to express an event that has often occurred, ὁπότε Κρήτηθεν ἵκοιτο Il., etc.:—also in oratio obliqua, Soph., etc.
II. in indirect phrases, ἴδμεν, ὁππότε Τηλέμαχος νεῖται when he "is to return", Od.; with opt., δέγμενος ὁππότε ναυσὶν ἐφορμηθεῖεν Il.
B. in causal sense, "for that, because, since", like Lat. quando for "quoniam", Theogn., Hdt., etc.: so ὁπότε γε, Lat. quandoquidem, Soph., Xen.
