ἀποκαλύπτω
apokalýptō · verb · “to reveal, unveil”
Apokalyptō means to unveil or reveal — to lift the cover off something hidden. The same root names the book of Revelation: God’s great unveiling.
Apokalyptō pictures lifting a veil — revealing what was previously hidden. Paul uses it of the gospel: the righteousness of God “revealed (apokalyptetai) from faith for faith” (Romans 1:17).
The noun form (apokalypsis) titles the last book of the Bible: the Apocalypse, the Revelation. The point is not chaos and dread but unveiling — God showing what he is doing and where history is going.
Definition: to take off the cover, i.e. disclose
KJV usage: reveal
