Origin & History
Origins and dates here are approximate summaries. Many idioms have disputed or unknown origins, and not every date has been checked against a historical dictionary, so treat specific dates and stories as a starting point rather than a citation.
An older phrase from the 1700s, probably nautical, for a very close call, such as a ship barely touching the bottom. The aviation 'touch-and-go' landing is a later use.
Recorded in English since the 18th century, long before aviation.
