Meaning
To lose an opportunity because one acted or decided too slowly, especially when others manage to act in time.
It often carries a note of regret or self-criticism, describing a chance that, once gone, generally can’t be recovered.
Origin
The image is straightforwardly literal: before modern transportation schedules with frequent departures, missing a scheduled passenger ship’s sailing at the dock could mean a genuinely long wait — sometimes weeks — for the next one, making a late arrival at the harbor a costly, memorable failure rather than a minor inconvenience. The figurative use, applying this concrete travel mishap to any missed opportunity in life or business, became common in English by the early 20th century, spreading alongside the growth of scheduled steamship and rail travel that made “catching” or “missing” a specific departure a shared, everyday experience for ordinary people rather than just sailors or the wealthy. Because the underlying experience (a fixed departure time that waits for no one) is so universal to modern transportation, similar “missed departure” idioms appear with different vehicles across many languages.
