What does prolongation mean?
Prolongation is the formal noun for the act of extending the duration of something, especially time, a process, or a state of affairs. It is common in administrative, scientific, legal, and literary writing: a prolongation of a hearing may mean an extension rather than a delay, while prolongation of life refers to making a lifespan longer. The word often carries a neutral or slightly technical tone, but it can suggest an undesirable extension, especially when something is being kept going longer than expected. In parliamentary and legal usage, it can also mean postponement or deferral. Although speakers use the verb prolong more often, prolongation is useful when naming the process as a formal concept rather than describing a single act. Its Latin ancestry reinforces its sense of lengthening: prolong ultimately combines the Latin prefix pro- and longus, meaning “long.”
