Thayer's Expanded Definition

ῤώννυμι: to make strong, to strengthen; perfect passive ἔρρωμαι (see Rho), to be strong, to thrive, prosper; hence, the 2 person (singular) imperative is the usual formula in closing a letter, ἔρρωσο, farewell: Acts 23:30 (R G); ἔρρωσθε, Acts 15:29 (2 Macc. 11:21; Xenophon, Cyril 4, 5, 33; Artemidorus Daldianus, oneir. 3, 44, others; ἔρρωσο καί ὑγίαινε, Dio Cassius, 61, 13).

STRONGS NT 4517a: σ [σ ,Sigma: the practice (adopted by Griesbach, Knapp, others, after H. Stephanus, et al.) of employing the character sigma σ in the middle of a compound word has been abandoned by the recent critical editors; cf. Winers Grammar, § 5, the passage cited; Lipsius, Gram. Untersuch., p. 122; Matthiae, § 1 Anm. 5; Alexander Buttmann (1873) Ausf. Sprchl. § 2 Anm. 3; Kühner, § 1 Anm. 1. Tdf. edition 8 writes sigma ς' also even at the end of a word, after the older manuscripts. On movable final sigma ς' see ἀχρἱσ', μεχρἱσ', ὁυτὡσ'. The (Ionic) combinations ῥς for ῥρ, and σς for ττ (cf. Fischer, Animadvers. ad Veller. etc. i., pp. 193f, 203; Kühner, § 31, pp. 124, 127), have become predominant (cf. ἄρσην, θαρσέω, θάρσος, ἀπαλλάσσω etc., γλῶσσα, ἥσσων (which see), θάλασσα, κηρύσσω, περισσός, πράσσω (which see), τάσσω, τέσσαρες, φυλάσσω, etc.), except in a few words, as κρείττων (which see), the derivatives of ἐλαττῶν (of which word both forms are used indiscriminately), ἥττημα, ἡττάω (yet see 2 Corinthians 12:13), etc.; cf. Buttmann, 7. Some proper names are spelled indifferently with one sigma ς' or with two; as, Ἐλισ῾σ᾿αιος. Zeta ζ' is occasionally substituted for sigma ς', especially before mu μ', see σβέννυμι, Σμύρνα (σμύρνα, cf. Sophocles Glossary, § 58, 3, and Lexicon, under the word; Tdf. Proleg., p. 80; WHs Appendix, p. 148; Buttmann, 5; Alexander Buttmann (1873) Ausf. Sprchl. § 3 Anm. 6; Bezae manuscript, Scrivener edition, p. xlviii.; Liddell and Scott, under the word Zeta ζ', I. 3, and Sigma ς', II. 14 c.); so also xi Ξ, as ξυμβαίνω 1 Peter 4:12 Rbez cf. Kühner, § 325, 5; Alexander Buttmann (1873) Ausf. Spr. as above; see ξύν.]

Vocabulary of the Greek NT

";sift,"; ";shake in a sieve"; (Luke 22:31) : cf. P Ryl II. 139.9 (A.D. 34) τὴν ἐπίσκεψιν ποιουμένου οὗ εἶχον σεννίου καὶ ψυγμοῦ, ";making an inspection of my . . . and drying-floor,"; where the editors think that the new word σέννιον may be connected with σινιάζω, and compare P Strass I, 45.11 (A.D. 312) εἰς τοὺς σ ̣εινι ̣ους τόπους, and note. The verb, like the late noun σινίον from which it comes, is of unknown derivation (Boisacq p. 866).
