Note 1.—For summary of conditional sentences, see Bt. 611; Gl 645; Gn. 1387; H.A. 891. VIII. FINAL CLAUSES 1. Pure final clauses (expressing purpose or motive) take the subjunctive when dependent on primary tenses, the optative when dependent on secondary tenses. The conjunction is ἵνα, ὡς, or ὅπως. E. g., τοῦτο πράττει ἵνα καλῶς ἔχῃ. τοῦτο ἔπραττε ἵνα καλῶς ἔχοι Bt. 590; Gl. 640; Gn. 365; H.A. 881. 2. Object clauses dependent on verbs denoting care, attention or effort, regularly take the future indicative ὅπως, though the future optative is possible when dependent on a secondary tense. E. g., φροντίζει ὅπως καλῶς ἕξει, ἐφρόντιζεν ὅπας καλῶς ἕζει (or ἕζοι, see note). Bt. 593; Gn. 1372; H.A. 885. 3. Subordinate clauses introduced by μή (trans. lest or that), and dependent on verbs denoting fear, caution or danger, take the subjunctive when dependent on primary tenses, the optative when dependent on secondary tenses. E. g., φοβεῖται μὴ τοῦτο πράττωμεν ἐφοβεῖτο μὴ τοῦτο πράττοιμεν (or πράττωμεν, see note). Bt. 593; Gl. 610; Gn. 1378. Note 1.—In rules 1-3, for greater vividness—as though using the language of the person who conceived the purpose—the subjunctive may be used even when dependent on a secondary tense (see examples above). Gl. 638; Gn. 1372. IX. INDIRECT DISCOURSE 1. A statement or question of a speaker or writer may be quoted directly, i. e., without change in the form of the language. E. g.: Direct: τοῦτο πράξω Indirect: λέγει { or { ὅτι τοῦτο πράξει. ἔλεγε { Bt. 668; Gl. 623; Gn. 1475. 2. Or it may be a change to adapt it to the form of the sentence of which it becomes a part. The form of change will depend on the introductory verb of saying, φημί, λέγω, or εἶπον. (1) If φημί, the main verb of the quotation will be changed to the infinitive mode of the same tense and voice. E. g., Direct: τοῦτο πράττω Indirect: φησί { or { τούτο πράττειν. ἔφη { (2) If λέγω with ὅτι or ὡς, no change will occur when dependent on a primary tense. When dependent on a secondary tense, indicatives and subjunctives may (not must) be changed to corresponding tenses (and voice) of the optative; optatives will remain unchanged. E. g.: Direct: τοῦτο πράξω Indirect: { λέγει ὅτι τοῦτο πράξει { ἔλεγε ὅτι τοῦτο πράξει (or πράξοι). (1) Note the change in person to indicate the change of speaker. (2) εἶπον as a verb of saying requires, and λέγω in the active voice prefers the ὅτι (ὡς) construction. (3) Where changes of mode might occasion doubt as to the form of the original direct discourse, no changes are made. E. g., the imperfect or pluperfect indicative with ἄν, the potential optative with ἄν, or the aorist indicative in a subordinate clause (cf. Bt. 675). Bt. 678; Gl. 624; Gn. 1523; 1481, 1497.
