Convergent - Word Puzzle

We speak and play word games every day. In those games, there are rules — the number of letters, or which letters can be used. But here, you can use all the letters you see on the screen, and you don’t know how many letters the answer contains. Yet can we still reach each other? Can ideas still be conveyed? Can consensus still be formed? Find out the missing words and name the one word that lies at the heart of this entire game.
