What is the significance of the name, "The Word"?

God / Jesus has many names which reveal something of His nature / character, e.g.: - Son of God (reveals His divine nature) - Son of Man (reveals His human nature) - etc. But "The Word" is more puzzling to me. Why is Jesus called "The Word" and what does it reveal about Him? > In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1
