ELI5: How can people be sure of a message sent in morse code? What if you missed a blink to write it down or only noticed after a while?

I never understood it in the movies. Then a TIL popped up a second ago about how a captured person did morsecode with blinking over the television. I just dont get it.

Believe it or not (according to what I've read), it's not that hard to pick up once you're trained to do it. In WW2, morse operators were often able to recognize and distinguish between the morse code signals of different senders.

It becomes no different than any language. Occasionally, when we speak or write, we misspell a word or drop a word or mix something up, but we are still able to completely understand what is being said and written. Morse (once you have learned that "language") is no different.
