ὅτι,

Epic dialect ὅττῐ (both in [Refs 8th c.BC+]: conjunction, to introduce an objective clause, that, after Verbs of seeing or knowing, thinking or saying; in [Refs 8th c.BC+] —Usage:

__I when ὅτι introduces a statement of fact:
__I.a in [Refs 8th c.BC+] always with indicative, the tense following the same rules as in English, ἤγγειλ᾽ ὅττι ῥά οἱ πόσις ἔκτοθι μίμνε πυλάων [Refs 8th c.BC+]
__I.b in Attic dialect, ὅτι takes indicative after primary tenses, indicative or optative after secondary tenses, e.g. ἐνδείκνυμαι ὅτι οὐκ ἔστι σοφός [Refs 5th c.BC+] news came that Megara had (literal has) revolted, [Refs 5th c.BC+]: sometimes optative and indicative are found in the same sentence, ἔλεγον, ὅτι Κῦρος μὲν τέθνηκεν, Ἀριαῖος δὲ πεφευγὼς.. εἴη [Refs 5th c.BC+].. and the accusative with infinitive are found together, [Refs 5th c.BC+]
__I.2 when ὅτι introduces a conditional sentence, the Constr. after ὅτι is the same as in independent conditional sentences, εἴ τις ἔροιτο, καθ᾽ ὁποίους νόμους δεῖ πολιτεύεσθαι, δῆλον ὅτι ἀποκρίναισθ᾽ ἄν.. it is manifest that you would answer.., [Refs 5th c.BC+]
__II ὅτι is frequently inserted pleonastic in introducing a quotation (where we use no conjunction and put inverted commas), λόγον τόνδε ἐκφαίνει ὁ Πρωτεύς, λέγων ὅτι ἐγὼ εἰ μὴ περὶ πολλοῦ ἡγεύμην.. [Refs 5th c.BC+]; καὶ ἐγὼ εἶπον, ὅ. ἡ αὐτή μοι ἀρχή ἐστι.. [Refs 5th c.BC+]; even where the quotation consists of one word,[Refs]
__II.2 ὅ. is also used pleonastic with the infinitive and accusative [Refs 5th c.BC+]; but ὅτι has frequently been wrongly inserted by the copyists, as if εἶπεν or λέγουσιν must be followed by it, as in [Refs 5th c.BC+]
__III ὅτι in Attic dialect frequently represents a whole sentence, especially in affirmative answers, οὐκοῦν.. τὸ ἀδικεῖν κάκιον ἂν εἴη τοῦ ἀδικεῖσθαι. Answ. δῆλον δὴ ὅτι (i.e. ὅτι κάκιον ἂν εἴη, or ὅτι ταῦτα οὕτως ἔχει) [Refs 5th c.BC+]; compare οἶδ᾽ ὅτι, ἴσθ᾽ ὅτι, οἶσθ᾽ ὅτι, [Refs 5th c.BC+] adverb
__III.2 what we make the subject of the Verb which follows ὅτι frequently stands in the preceding clause, Αυκάονας δὲ καὶ αὐτοὶ εἴδομεν, ὅτι.. καρποῦνται (for εἴδομεν, ὅτι Λυκάονες καρποῦνται) [Refs 5th c.BC+]
__IV ὅτι sometimes = with regard to the fact that, ὅτι.. οὔ φησι.. ὄνομα εἶναι, ὑποπτεύω αὐτὸν σκώπτειν [Refs 5th c.BC+]
__V οὐχ ὅ..., ἀλλὰ or ἀλλὰ καὶ.., οὐχ ὅ. ὁ Κρίτων ἐν ἡσυχίᾳ ἦν, ἀλλὰ οἱ φίλοι αὐτοῦ not only [Refs 1st c.AD+].., but his friends, [Refs 5th c.BC+] not only the powers in Europe, but.., [Refs 5th c.BC+]., not followed by a second clause, means although, οὐχ ὅ. παίζει καί φησι [Refs 5th c.BC+]
__V.2 for ὅτι μή, see at {ὅ τι} 11.
__B as a causal Particle, for that, because, generally after Verbs of feeling, [Refs 8th c.BC+]: but without such a Verb, ὃν περὶ πάσης τῖεν ὁμηλικίης, ὅτι οἱ φρεσὶν ἄρτια ᾔδη [Refs 8th c.BC+]
__B.b followed by τί, ὅτι τ; why? (literal because why?) [Refs 4th c.BC+]; ὅτι τί δ; [Refs 5th c.BC+]; ὅτι δὴ τί μάλιστ; [Refs 5th c.BC+]; ὅτι δὴ τί γ; [Refs]; compare ὁτιή.
__B.2 seeing that, in giving the reason for saying what is said, γλαυκὴ δέ σε τίκτε θάλασσα.. ὅτι τοι νόος ἐστὶν ἀπηνής as is proved by the fact that.., [Refs 8th c.BC+] (ὅ τ᾽) probably always represents ὅτε (ὅ τε): there are no examples of ὅττ᾽: hiatus after ὅτι is permitted in Comedy texts, [Refs 5th c.BC+]
