COMMON If someone in authority gives someone or something the green light or gives the green light to someone or something, they allow someone to do something or something to happen. He has finally been given the green light to build five new houses on the land. Note: You can also say that someone gets the green light. I've got a bunch more songs, and if I can get the green light from my manager, I'd like to go straight back in and record some more. Note: People use a green light to mean permission from someone in authority. Is that a green light for interest-rate cuts?
