Continuity means an unbroken and consistent connection over time. When a TV series maintains continuity, the events and details from earlier episodes stay true in later ones: if a character breaks their arm in episode three, they should still have a cast in episode four. When a business experiences continuity of leadership, the same person or team stays in charge, providing steady direction.

The word captures the idea that things flow smoothly from one moment to the next without sudden breaks or contradictions. A river has continuity as it flows from its source to the sea. Your memories give your life continuity, connecting who you were yesterday to who you are today.

In mathematics, continuity describes a line or curve with no gaps or jumps. In filmmaking, a continuity error happens when something changes between shots that shouldn't have changed, like an actor's hair suddenly looking different or a glass that was full becoming empty without anyone drinking from it.

The opposite of continuity is disruption or discontinuity: imagine reading a book where chapter five suddenly forgets everything that happened in chapter four. Continuity gives things coherence and reliability. When something maintains continuity, you can count on it staying consistent and connected to what came before.
