1100 glṓssa – tongue, used of flowing speech; (figuratively) speaking, inspired by God, like the evidence of tongues-speaking supplied by the Lord in the book of Acts to demonstrate the arrival of the new age of the covenant (i.e. NT times).
[The normative experience of the 120 believers received "tongues (1100 /glṓssa) as of fire" (Ac 2:3) and miraculously spoke in other actual languages, i.e. that they could not speak before (Ac 2:4f). This sign was repeated in Ac 10:46, 19:6 – furnishing ample proof (three attestations) that the Lord had incorporated all believers into Christ's (mystical) body (1 Cor 12:13).]
