Not completed or fulfilled, especially in a romantic or sexual context.
Their marriage remained unconsummated due to personal reasons.
Unconsummated → It is formed from "un-" (meaning not), "consummare" (from Latin, meaning to complete or fulfill), and "-ed" (a suffix indicating a past action). The word "unconsummated" means not completed or fulfilled, particularly in the context of a relationship or agreement.
Think of 'not' ('un-') completing something ('consummare') — that's why unconsummated means something that has not been completed.
