IPA: /ˈpriːkwəl/
KK: /ˈpriːkwəl/
A story or work that happens before another story, often providing background or context to the original work.
The new movie is a prequel to the popular series, showing how the characters first met.
Prequel → It is formed from "pre-" (meaning before) and "quel" (from Latin "qualis", meaning of what kind). The word "prequel" refers to a work that is set before the events of another work, essentially telling the story of what happened prior.
Think of 'pre-' meaning 'before' — a prequel is a story that comes before another story.
