νυνί (νῦν with iota demonstr. [Kriiger § 25, 6, 4 sq.; Kiihner § 180, 6. (Jelf § 160, e.); Bitm. Gram. § 80, 2]), in Attic now, at this very moment (precisely now, neither before nor after; Lat. nune ipsum), and only of Time, almost always with the pres., very rarely with the fut. (cf. Lob. ad Phryn. p. 19). Not found in the N. T. exc. in the writ. of Paul and in a few places in Acts and the Ep. to the Heb.; and it differs here in no respect from the simple viv; cf.
