A primary word; "else," i.e. Different (in many applications) -- more, one (another), (an-, some an-)other(-s, -wise).
a. absolutely: Matthew 27:42; Matthew 20:3; Mark 6:15; Acts 19:32; Acts 21:34 (ἄλλοι μέν ἄλλο), and often,
b. as an adjective: Matthew 2:12; Matthew 4:21; John 14:16; 1 Corinthians 10:29 (ἄλλη συνείδησις, i. e. ἡ συνείδησις ἄλλου τίνος).
c. with the article: ὁ ἄλλος the other (of two), Matthew 5:39; Matthew 12:13, etc. (cf. Buttmann, 32 (28), 122 (107)); οἱ ἄλλοι all others, the remainder, the rest: John 21:8; 1 Corinthians 14:29. [SYNONYMS: ἄλλος, ἕτερος: ἄλλος as compared with ἕτερος denotes numerical in distinction from qualitative difference; ἄλλος adds ('one besides'), ἕτερος distinguishes ('one of two'); every ἕτερος is an ἄλλος, but not every ἄλλος is a ἕτερος; ἄλλος generally 'denotes simply distinction of individuals, ἕτερος involves the secondary idea of difference of kind'; e. g. 2 Corinthians 11:4; Galatians 1:6, 7. See Lightfoot and Meyer on the latter passage; Trench, § xcv.; Schmidt, chapter 198.]
