What does inundation mean?
Inundation means the flooding of an area by water and, by extension, an overwhelming abundance of people, objects, information, or requests. Its literal use refers to water covering land, buildings, or streets, often with disruptive consequences. Figuratively, it describes a sudden or overwhelming arrival: a website may experience an inundation of traffic, while a public announcement may produce an inundation of inquiries. The word is formal and carries a sense of excess, force, and difficulty in controlling what has arrived. Rather than simply suggesting a large quantity, inundation emphasizes how much there is and how thoroughly it overwhelms the surroundings. The word is especially useful for describing events or conditions that exceed ordinary capacity, whether through water, attention, information, or competing demands.

Where does inundation come from?
Inundation comes from Latin inundatio, a noun derived from inundare, “to flood” or “to overwhelm.” The Latin verb combines the prefix in- with unda, “wave,” reflecting its association with water rising over the land. The English noun developed through French and has long been used both for literal flooding and for figurative abundance. Its English relatives include inundate and its inflected forms, while related Latin-root vocabulary includes abundancy.
How inundation is actually used
