🎓 Common Learner Point
It's about a very small margin. You use it when something could easily have gone wrong, not when you did well with room to spare.
The wording is fixed. By the skin of my / your / his teeth. You can change the possessive, but not the nouns.
It works for success and escape. You can say you escaped by the skin of your teeth or passed by the skin of your teeth.
🕵️ Where Does It Come From? A Very Old Line
This is the OddLingo part: the words come from a very old book.
What we can say:
- The phrase appears in the Book of Job (19:20) in the English Bible. The King James translation reads: "I am escaped with the skin of my teeth".
- An earlier English Bible, the Geneva Bible, has the words "skinne of my tethe".
- Scholars aren't sure exactly what the original Hebrew meant, and the English phrase became a proverb for a narrow escape.
So the idiom is old, and the joke is that nobody can be sure what the "skin" was.
💡 The OddLingo Trick
Picture a tiny sliver on a tooth. If you only just escaped, you were hanging on by something that thin. Skin of your teeth = almost nothing.
