Green light meaning: permission to go ahead

To approve a plan and let it start, like a traffic light turning green. In the news, though, the whole phrase often shrinks to one word with an unusual past tense.

Give the green light means to allow something to start or to approve a plan. The image comes from traffic lights. People mostly say it about decisions by bosses, banks and the authorities: one side gives the green light (give), and the other side gets it (get).

What changed

First versionThe director gave the green street to our project.

RevisionThe director gave the green light to our project.

Green street sounds like a literal translation: there's no such idiom in English, and a native speaker will just hear “a green street”. For permission to start, the only option is green light.

Cambridge Dictionary

In news and business English, the phrase is often squeezed into one verb, greenlight, and its past tense is usually greenlit: The studio has greenlit a second season. A close synonym is give the go-ahead: The boss gave us the go-ahead. Both are neutral and work even in an essay.

(got / gave)

got — The permission came from the director, so we received it: got. Gave would mean we gave the permission ourselves, and then from the director wouldn't fit the sentence.

Describe a plan you needed to get approved. Say who gave you the green light and what you were able to do after that.

My landlord gave me the green light to paint the kitchen, so I spent the weekend making it bright yellow.
