shorten

This verb describes the act of reduction, whether applied to physical dimensions or temporal spans. It carries a neutral, functional connotation, focusing on the result of a decrease in length or time rather than the method used to achieve it. In professional settings, it often implies a strategic or necessary adjustment to fit a specific requirement or constraint.

When applied to time, the word suggests a compression of a schedule or a truncation of an event. It differs from "curtail" in that "shorten" is more general and less likely to imply a premature or forced ending, whereas "curtail" often suggests a restriction or a cutting off of something for the sake of economy or control.
