postpone

This term conveys a deliberate decision to shift a scheduled event to a future date. It implies a level of intentionality and planning, often suggesting that the event will definitely happen, just not at the original time. It is commonly used in professional, administrative, or formal social contexts. While similar to delay, this word specifically focuses on the rescheduling aspect rather than just a slowing of progress or an accidental setback. It suggests a controlled adjustment of a timeline rather than an unplanned interruption.
