IPA: /ˈplɒtlaɪn/
KK: /ˈplɑtˌlaɪn/
The main story or sequence of events in a book, movie, or play.
The plotline of the movie kept the audience on the edge of their seats.
Plotline → It is formed from "plot" (from Old English *plott*, meaning a small piece of ground or a plan) and "line" (from Latin *linea*, meaning a string or line). The word "plotline" refers to the sequence of events or the main storyline in a narrative, essentially outlining the plan of the story.
Think of a 'plot' as a 'plan' for a story and a 'line' as a sequence — together, they create the main sequence of events in a narrative.
