The act of rewinding.
"I had to rewind the tape so I could hear what he said at the beginning."
To wind (something) again.
"After accidentally skipping the chorus, I had to rewind the cassette tape before it could continue playing."
This word combines the prefix re- with wind to mean turning something back around. It originally referred to rewinding a film strip or tape, though it is now used more broadly for reversing any process.
