What does 'touch and go' mean?

What it means: A situation that is uncertain and could go either way — often with serious consequences if it goes wrong. Precarious and unpredictable.

"It was touch and go for a while after the operation."
"The project launch was touch and go right up to the deadline."
"Whether we'd make the flight was touch and go."

The origin: Aviation — a "touch and go" is a training manoeuvre where a plane lands briefly and immediately takes off again. In everyday use, the phrase captured the idea of something barely working, hovering between success and failure.

What it implies: The outcome was uncertain, and the situation required luck or careful handling to resolve well. Looking back on it, things could easily have gone the other way.

• "It was uncertain for a while" — plain
• "It could have gone either way" — specific
• "We were on a knife-edge" — British, more dramatic

Register: Casual to professional. Common in conversation and informal writing.
