🕰️ Wait... Time Flies?
TIME + FLIES

Does time feel as fast as a bird? ✅
We say flies when something moves quickly, like a bird in the sky. You cannot stop a bird, and you cannot stop time. It is already gone.
Notice that the verb is flies, not fly: time is one thing, so the verb has an s.

🕵️ Where Did It Come From?
This idea is more than 2,000 years old. The Roman poet Virgil wrote it in a long poem called the Georgics, around 29 BC. His Latin line says that time flees, and it cannot be brought back.
The famous Latin saying tempus fugit comes from it. Tempus means time, and fugit means flees or flies.
Another Roman writer, Seneca, noticed that Virgil said flies and not goes. We do not know when the English words time flies first appeared.
