[*] 71. The future sometimes denotes a present intention, expectation, or necessity that something shall be done, in which sense the periphrastic form with μέλλω (73) is more common. E.g.
- “Τί διαφέρουσι τῶν ἐξ ἀνάγκης κακοπαθούντων, εἴ γε πεινήσουσι καὶ διψήσουσι καὶ ῥιγήσουσι καὶ ἀγρυπνήσουσι;” “if they are to endure hunger and thirst, etc.” XEN. Mem. ii. 1, 17 . (Here εἰ μέλλουσι πεινῆν καὶ διψῆν, etc., would be more common, as in the last example under 73.）
- “Αἶρε πλῆκτρον, εἰ μαχεῖ,” “raise your spur, if you are going to fight.” AR. Av. 759.
