Greek Conjunction

ἄρᾰ, Epic dialect ῥά (which is enclitic and used after monosyllables, ἦ, ὅς, γάρ, etc, or words ending in a vowel or diphthong, e.g. ἐπεί), before a consonant ἄρ (perhaps cf. Lithuanian i[rtilde] 'and'): expressing consequence, then, or mere succession, there and then, and in many derived uses. A) EARLIER USAGE: to denote, A.I) immediate transition, there and then, straightway, ὣς φάτο βῆ δ᾽ ἄρ᾽ Ὄνειρος[Refs 8th c.BC+]: after a participle, ὣς εἰπὼν κατ᾽ ἄρ᾽ ἕζετο[Refs 5th c.BC+]; οὕτως ἄρα[Refs 5th c.BC+]; often in apodosi, as αὐτὰρ ἐπεὶ δὴ θηήσατο. αὐτίκ᾽ ἄρ᾽ ἤλυθεν[Refs 8th c.BC+]: in enumerations, e. g. in Homer's catalogue, then, next, οἱ δ᾽ ἄρ᾽ Ἀθήνας εἶχον[Refs]; so in genealogies, Σίσυφος. ὁ δ᾽ ἄ. Γλαῦκον τέκεθ᾽ υἱόν[Refs] A.I.2) to draw attention, mark you! τὸν τρεῖς μὲν ἐπιρρήσσεσκον. τῶν ἄλλων Ἀχιλεὺς δ᾽ ἄρ᾽ ἐπιρρήσσεσκε καὶ οἶος[Refs]: to point a moral or general statement, φευγόντων δ᾽ οὔτ᾽ ἂρ κλέος ὄρνυται οὔτε τις ἀλκή[Refs] A.II) connexion, such as, A.II.1) that of antecedent and consequent, οἰνοχόει. ἄσβεστος δ᾽ ἄρ᾽ ἐνῶρτο γέλως[Refs]: also in questions, τίς τ᾽ ἄρ τῶν ὄχ᾽ ἄριστος ἔη; who then (say you) was? [Refs]he it was, whom, [Refs], thus, then he spoke.—This usage is universal in Greek. A.II.2) explanation of that which precedes, χωόμενον κατὰ θυμὸν ἐϋζώνοιο γυναικὸς τήν ῥα. ἀπηύρων whom (and for this cause he was angry) they had taken away, [Refs]; εἰ μὴ ὑπερφίαλον ἔπος ἔκβαλε. φῆ ῥ᾽ ἀέκητι θεῶν φυγέειν for he said, [Refs 8th c.BC+]; so with relatives, ἐκ δ᾽ ἔθορε κλῆρος ὃν ἄρ᾽ ἤθελον αὐτοί the very one which, [Refs 8th c.BC+] B) LATER USAGE, always with inferential force: 1. in drawing conclusions (more subjective than οὖν), ἄριστον ἄ. ἡ εὐδαιμονία[Refs 4th c.BC+]: especially by way of informal inference, as it seems, οὐκ ἄ. σοί γε πατὴρ ἦν Πηλεύς[Refs 8th c.BC+]; οὕτω κοινόν τι ἄ. χαρᾷ καὶ λύπῃ δάκρυά ἐστιν so true is it that, [Refs 5th c.BC+]; so in announcing the discovery or correction of an error, as οὐκ ἐννενοήκαμεν ὅτι εἰσὶν ἄ. [Refs 5th c.BC+]; εἰκότως ἄ. οὐκ ἐγίγνετο· ὡς γὰρ ἐγὼ νῦν πυνθάνομαι. [Refs 5th c.BC+] B.2) in questions, expressing the anxiety of the questioner, τίς ἄ. ῥύσετα; who is there to save? [Refs 4th c.BC+]; so in exclamations to heighten the expression of emotion, οἵαν ἄρ᾽ ἥβην. ἀπώλεσεν what a band of youth was that! [Refs]; so ὡς ἄρα[Refs 5th c.BC+]; πῶς ἄ; οὕτως ἄ, etc; ἄ. alone, ἔζης ἄ.[Refs 5th c.BC+]: especially in ironical comments, [Refs 5th c.BC+] B.3) epexegetic, namely, ἐρῶ, ὡς ἄ. [Refs 5th c.BC+] B.4) for τοι ἄρα, τἄρα, see entry τοι [Refs] B.5) εἰ (or ἐάν) μὴ ἄ. unless perhaps, [Refs 5th c.BC+]; separated from εἰ μή, [Refs 5th c.BC+] B.6) in hypothetical clauses, to indicate the improbability of the supposition, ἢν ἄ. ποτὲ κατὰ γῆν βιασθῶσιν[Refs 5th c.BC+]; or simply, perhaps (sometimes separated from εἰ), εἴ τις οὖν ὑμῶν ἄ. ὑπελάμβανεν[Refs 5th c.BC+] C) IN CRASIS, frequently τἄρα, μεντἄρα, οὐτἄρα: also δήξομἄρα for δήξομαι ἄ, [Refs 5th c.BC+]; οἰμώξετἄρα, κλαύσἄρα, [Refs 5th c.BC+] D) ἄρα never stands first in the sentence in Classical Greek [Refs 4th c.BC+], but is found at the beginning of an apodosis in [NT], and first in a sentence, [NT+2nd c.AD+]; in conclusion of syllogism, [Refs 2nd c.AD+]

Greek

a particle denoting an inference more or less decisive (as follows); haply, (what) manner (of man), no doubt, perhaps, so be, then, therefore, truly, wherefore; probably from g142 (αἴρω) (through the idea of drawing a conclusion)
