B IN CONDITIONS, if:
B.I with INDIC.,
B.I.1 with all tenses (for future, see below [Refs]if this is so, it will be.., [Refs 8th c.BC+]: any form of the Verb may stand in apodosi, εἰ θεοί τι δρῶσιν αἰσχρόν, οὐκ εἰσὶν θεοί [Refs 8th c.BC+]; εἰ οὗτοι ὀρθῶς ἀπέστησαν, ὑμεῖς ἂν οὐ χρεὼν ἄρχοιτε if these were right in their revolt, (it would follow that) you rule when you have no right, [Refs 5th c.BC+]
B.I.1.b to express a general condition, if ever, whenever, sometimes with present, εἴ τις δύο ἢ καὶ πλείους τις ἡμέρας λογίζεται, μάταιός ἐστιν [Refs 5th c.BC+]: with imperfect, εἴ τίς τι ἠρώτα ἀπεκρίνοντο [Refs 5th c.BC+]: rarely with aorist, [Refs 1st c.BC+]

B.II.1 when the apodosis is future, to express a future condition more distinctly and vividly than εἰ with optative, but less so than εἰ with future indicative (above [Refs]; εἰ δέ κεν ὣς ἕρξῃς καί τοι πείθωνται Ἀχαιοί, γνώσῃ ἔπειθ᾽.. if thou do thus.., thou shalt know, [Refs 8th c.BC+]; ἂν μὴ νῦν ἐθέλωμεν ἐκεῖ πολεμεῖν αὐτῷ, ἐνθάδ᾽ ἴσως ἀναγκασθησόμεθα τοῦτο ποιεῖν if we be not now willing, [Refs 5th c.BC+]
B.II.2 when the apodosis is present, denoting customary or repeated action, to express a general condition, if ever, ἤν ποτε δασμὸς ἵκηται, σοὶ τὸ γέρας πολὺ μεῖζον (i.e. ἐστί) whenever a division comes, your prize is (always) greater, [Refs 8th c.BC+]; ἢν ἐγγὺς ἔλθῃ θάνατος, οὐδεὶς βούλεται θνῄσκειν if death come near, [Refs 5th c.BC+]; with ἄν omitted, εἴ περ γάρ τε χόλον.. καταπέψῃ ἀλλά.. ἔχει κότον [Refs 8th c.BC+]

B.III with OPTATIVE (never with ἄν in early Gr., later ἐάν with optative, [Refs 5th c.AD+]
B.III.1 to express a future condition less definitely than ἐάν with subjunctive, usually with optative with ἄν in apodosis, ἦ κεν γηθήσαι Πρίαμος Πριάμοιό τε παῖδες.. εἰ σφῶιν τάδε πάντα πυθοίατο μαρναμένοιιν surely they would exult, if they should hear.., [Refs 8th c.BC+]: future optative is falsa lectio in [Refs 5th c.BC+]: with present indicative in apodosis, [Refs 6th c.BC+]: with future indicative, [Refs 5th c.BC+]
B.III.1.b in Hom.sometimes with present optative, to express an unfulfilled present condition, εἰ μὲν νῦν ἐπὶ ἄλλῳ ἀεθλεύοιμεν, ἦ τ᾽ ἂν ἐγὼ τὰ πρῶτα φεροίμην if we were now contending, etc., [Refs 8th c.BC+]
B.III.2 when the apodosis is past, denoting customary or repeated action, to express a general condition in past time (corresponding to use of subjunctive in present time, above [Refs]; once in [Refs 8th c.BC+]; εἰ δέ τινας θορυβουμένους αἴσθοιτο.., κατασβεννύναι τὴν ταραχὴν ἐπειρᾶτο if he should see (whenever he saw) any troops in confusion, he (always) tried, [Refs 5th c.BC+]; εἴ τις ἀντείποι, εὐθὺς ἐτεθνήκει if any one made objection, he was a dead man at once, [Refs 5th c.BC+]: indicative and optative are found in same sentence, ἐμίσει, οὐκ εἴ τις κακῶς πάσχων ἠμύνετο, ἀλλ᾽ εἴ τις εὐεργετούμενος ἀχάριστος φαίνοιτο [Refs 5th c.BC+]
B.III.3 in oratio obliqua after past tenses, representing ἐάν with subjunctive or εἰ with a primary (never an historical) tense of the indicative in oratio recta, ἐλογίζοντο ὡς, εἰ μὴ μάχοιντο, ἀποστήσοιντο αἱ πόλεις (representing ἐὰν μὴ μαχώμεθα, ἀποστήσονται) [Refs 5th c.BC+]; ἔλεγεν ὅτι, εἰ βλαβερὰ πεπραχὼς εἴη, δίκαιος εἴη ζημιοῦσθαι (representing εἰ βλαβερὰ πέπραχε, δίκαιός ἐστι)[Refs]; εἰ δέ τινα φεύγοντα λήψοιτο, προηγόρευεν ὅτι ὡς πολεμίῳ χρήσοιτο (representing εἴ τινα λήψομαι, χρήσομαι) [Refs]; also, where oratio obliqua is implied in the leading clause, οὐκ ἦν τοῦ πολέμου πέρας Φιλίππῳ, εἰ μὴ Θηβαίους.. ἐχθροὺς ποιήσειε τῇ πόλει, i.e. Philip thought there would be no end to the war, unless he should make.. (his thought having been ἐὰν μὴ ποιήσω), [Refs 5th c.BC+]
B.III.4 with optative with ἄν, only when the clause serves as apodosis as well as protasis,[Refs 5th c.BC+]
B.IV with infinitive, in oratio obliqua, only in [Refs 5th c.BC+]
B.V after Verbs denoting wonder, delight, indignation, disappointment, contentment, and similar emotions, εἰ with indicative is used instead of ὅτι, to express the object of the feeling in a hypothetical form, θαυμάζω εἰ μηδεὶς ὑμῶν μήτ᾽ ἐνθυμεῖται μήτ᾽ ὀργίζεται, ὁρῶν.. I wonder that no one of you is either concerned or angry when he sees.., [Refs 4th c.BC+]: after past tenses, ἐθαύμασε δ᾽ εἰ μὴ φανερόν ἐστιν [Refs 5th c.BC+]; ἐθαύμαζε δ᾽ εἴ τις ἀρετὴν ἐπαγγελλόμενος ἀργύριον πράττοιτο he wondered that any one should demand money, [Refs]; ἔχαιρον ἀγαπῶν εἴ τις ἐάσοι I rejoiced, being content if any one should let it pass, [Refs 5th c.BC+] —in this use the _negative_ οὐ is also found, ἀγανακτῶ εἰ ὁ Φίλιππος ἁρπάζων οὐ λυπεῖ [Refs 5th c.BC+]
B.VI in citing a fact as a ground of argument or appeal, as surely as, since, εἴ ποτ᾽ ἔην γε if there was [as there was], i.e. as sure as there was such an one, [Refs 8th c.BC+]; πολλοὺς γὰρ οἶκε εἶναι εὐπετέστερον διαβάλλειν ἢ ἕνα, εἰ Κλεομένεα μὲν μοῦνον οὐκ οἷός τε ἐγένετο διαβαλεῖν, τρεῖς δὲ μυριάδας Ἀθηναίων ἐποίησε τοῦτο it seems easier to deceive many than one, if (as was the fact, i.e. since) he was not able.., [Refs 5th c.BC+]
