 The word originated as a compound of - 'all' (the form taken by the word πᾶν, neuter of πᾶς 'all', when that is used as a prefix) and the word 'assembly' (an Aeolic dialect form, corresponding to the Attic or Ionic form ).Compounded, these gave 'general or national assembly, especially a festival in honour of a god' and the derived adjective 'of or for a public assembly or festival'.In Hellenistic Greek the noun came also to mean 'a festal oration, laudatory speech', and the adjective 'of or relating to a eulogy, flattering'.
