momentary
brief / fleeting / transient / short-lived
Adjective
This term describes a duration so brief that it is almost instantaneous, often capturing a flicker of emotion or a sudden interruption. It carries a connotation of transience, suggesting that the state described is an exception to a more permanent condition. In usage, it frequently modifies sudden psychological shifts or physical pauses. While similar to "brief," it emphasizes the fleeting nature of the event, often implying that the experience vanished as quickly as it appeared.
