The grand opening is a term that describes the launch of a new business or the beginning of an event. The word "grand" refers to something magnificent, impressive, and important. It evokes a sense of excitement and anticipation. On the other hand, an antonym for grand opening is a muted start or a quiet opening. A muted start is a low-key affair with little fanfare or hype. It is usually done for practical reasons, such as budget constraints or a desire for simplicity. A quiet opening, on the other hand, is a more controlled event with a limited audience. It is often done for high-end or exclusive products or services.
