92 Trent A. Rogers avoid divorcing the preposition from its object, this positioning does allow an adjectival modifier to be introduced71. c. Interrogative (so): Smyth states that in Classical Greek, the interrogative use is typically with the aorist72. But this pattern does not play out in the limited interrogative use in John as all occurrences are in the present (1:21, 1:25, [8:5 not in P66], 9:19). The interrogative use of οὖν is always also inferential as the question rests on a deduction from the previous sentence. Although the interrogative use makes a deduction from the pre- ceding material, I wish to distinguish it from the deductive use because the interrogative οὖν functions to deny or question the validity of the logical deduction. The occurrences are limited in P66, and all examples of the interrogative οὖν occur with an interrogative marker: τί in 1:21, 25 and πῶς in 9:19. When it ap- pears in a collocation coupled with an interrogative marker, οὖν draws attention to the logical connection between the question- ing sentence and the preceding in sentence. The interrogative, οὐκοῦν, occurs in John 18:37. 9:19: και επηρωτησαν αυτους λεγοντες ουτος εστιν ο ϋϊος ϋμων ον ϋμις λεγετε οτι τυφλος εγεννηθη πως ουν αρτι βλεπει73. The “Jews” make a deductive question based on the content of John 9:18. If it is true that he was born blind, how could it follow that he now sees? So the interrogative use of οὖν questions the validity of the deduction. d. Comparative (likewise, similarly): this use highlights the similar- ity between two sentences. To my knowledge, no grammarians have proposed a comparative use of οὖν, so I will proceed with some degree of caution74. There are at most four occurrences in P66: 3:29, 8:38, 13:14, 16:22. Obviously, this belongs under the broader categorization of inferential use because it shows how one sentence is logically related to the previous sentence. All of the comparative uses occur in direct discourse. 71 This example is complicated by the attributive positioning of the demonstrative adjec- tive. 72 Smyth, Grammar, 2962. Mantey, “Meaning”, 52, does not distinguish the interroga- tive use from the general inferential use. 73 “And they asked them saying, “‘Is this your son whom you say was born blind? How then does he see’”? 74 The closest is Abbott, Grammar, §§ 2194-2197, who proposes that οὖν can denote correspondence, but he still translates οὖν as “therefore” which seems to assume an infer- ential use.
