When Elizabeth had her baby, people asked her what his name would be. She answered that his name would be John, even though no one else in her family had that name. So, they asked Zechariah, because he might want the baby named after him. He wrote on a tablet that the baby's name was John! And that's when he was able to talk again. He knew this was no ordinary baby. He spoke through the power of the Holy Spirit, and said that John was going to prepare the way for the Savior to come.
