Usage: Use "moment" to refer to an indefinite but very short duration, such as waiting just a moment before hanging up. It often implies a pause in action rather than a specific clock time like 3:00 PM.
The word "moment" entered English via the Middle English and Old French forms of the Latin mōmentum. Originally referring to a small weight or turning point, it evolved to mean a brief period of time.
