From eido; a view, i.e. Form (literally or figuratively) -- appearance, fashion, shape, sight.
see GREEK eido
1. the external oppearance, form, figure, shape, (so from Homer down): John 5:37; σωματικῷ εἴδει, Luke 3:22; τό εἶδος τοῦ προσώπου αὐτοῦ, Luke 9:29; διά εἴδους, as encompassed with the visible appearance (of eternal things) (see διά, A. I. 2), 2 Corinthians 5:7, — commonly explained, by sight i. e. beholding (Luth.:im Schauen); but no example has yet been adduced from any Greek writings in which εἶδος is used actively, like the Latin species, of vision; (στόμα κατά στόμα, ἐν εἴδει, καί οὐ δἰ ὁραμάτων καί ἐνυπνίων, Clement. homil. 17, 18; cf. Numbers 12:8 the Sept.).
2. form, kind: ἀπό παντός εἴδους πονηροῦ ἀπέχεσθε, i. e. from every kind of evil or wrong, 1 Thessalonians 5:22 (cf.πονηρός, under the end); (Josephus, Antiquities 10, 3, 1 πᾶν εἶδος πονηρίας. The Greeks, especially Plato, oppose τό εἶδος to τό γένος, as the Latin does species to genus. Cf. Schmidt, chapter 182, 2).
