IPA: /ˈʌndərˌplɒt/
KK: /ˈʌndərˌplɑt/
A secondary or underlying plot in a story that runs alongside the main plot, often adding depth or complexity to the narrative.
The novel's underplot revealed the protagonist's hidden struggles and relationships.
Underplot → It is formed from "under-" (meaning beneath or below) and "plot" (from Old French *plot*, meaning a small piece of ground or a plan). The word refers to a secondary or hidden storyline that exists beneath the main plot of a narrative.
Think of something that exists 'beneath' ('under-') the main story or plan ('plot') — that's why underplot refers to a hidden or secondary storyline.
