(G5926) Synonyms for Darkness: skotos (σκότος G4655), gnophos (γνόφος G1105), zophos (ζόφος G2217), achlys (ἀχλύς G887).

(σκότος G4655) skotos is a general word, meaning darkness in any sense. gnophos usually refers to darkness that accompanies a storm. zophos meant originally the gloom of twilight. It was then applied in classical Greek to the darkness of the underworld, the gloom of a sunless region. The latter meaning seems to be practically the one which the word has in the N. T. achlys is specifically a misty darkness.
