80 Trent A. Rogers but there is some variation in this positioning17. By far the commonest verb tense is the aorist with about 150 occurrences with the present and imperfect each accounting for about 25 occurrences and the perfect for less than 5. Also commonest is the indicative mood, and where an intro- ductory participial clause contains οὖν, οὖν modifies the verb of the main clause. Frequently δέ occurs in a clause subsequent to οὖν. There is some variation in the number of intervening words with an average of 13 words coming between the two. John 11:41 and 6:5 are the extremes with 3 and 22 words intervening οὖν and δέ respectively. The subsequent δέ can serve several functions: clarification, explanation, contrast, continuation, indication of change of speaker, result, or progression to new subject18. When οὖν occurs in a collocation with a certain temporal markers—ὅτε, τότε, πάλιν, ὡς —it is always continuative: While any word that is not postpositive can occur in the first position, there are three collocations that P66 commonly employs: article—οὖν—noun19, verb—οὖν—dative,20 and verb—οὖν—subject21. Mantey comments on the difficulty of determining the syntactical function of οὖν: “Οὖν is a particle and usually comes between two para- graphs of thought. An accurate knowledge of the immediate words is not only necessary but also of the immediate sentences before and after it... the possible meanings for a particle are almost legion”22. The classifica- tion of the function of οὖν depends on the type of relationship that it conveys between two sentences or paragraphs. BDAG lists the primary use of οὖν as inferential and its secondary use as transitional23. In the 17 See G. L. Cooper III, Attic Prose Syntax (Ann Arbor 1998) 1413. BDF, Grammar, 475.2, J. D. Denniston, The Greek Particles (2nd ed. rev. K. J. Dover; Indianapolis 1950) 427. 18 This list is not exhaustive. Robertson, Grammar, 1183 states “The ordinary narrative use [of δέ] (continuative) I conceive to be the original use; the adversative the developed and later construction”. 19 E.g., 9:8; 11:20, 31, 32, 54; 12:1, 3, 19, 29; 18:3, 19; 19:23, 31 20 E.g., 1:22; 4:9, 33; 6:7, 35, 53; 7:16, 47; 8:13, 19, 23, 24, 25, 28, 39, 41; 9:17, 25, 26; 18:17, 25, 31, 37; 19:21; 20:21, 25. 21 E.g., 2:18, 20; 4:53; 5:10, 19; 6:10, 41, 67; 7:15, 25, 33, 35, 45; 8:22, 31, 57; 9:10, 20; 10:24; 11:3, 12, 16, 21, 36, 47; 12:7, 9, 17, 28; 18:11, 16, 29; 19:1; 20:3, 20; 21:7, 11. 22 Mantey, “Meaning”, iv-v. 23 BDAG, οὖν; contra Black, Conjunctions, 258-9. J. W. Donaldson, A Complete Greek Grammar for the Use of Students (2d ed.; London 1859) 271, actually seems to deny the inferential use in his brief treatment: “It does not imply a logical inference, like ἄρα, but merely recalls attention to something, which has already been said, in the way of confirma- tion or correction”. At the other extreme, Abbott, Grammar, §§ 2198-2200, translates οὖν exclusively as “therefore” in the narrative material which suggests that he only maintains the inferential use.
