The word "influx" refers to the arrival or introduction of a large number of people or things into a place. It often describes a situation where there is a considerable flow or movement into a particular area, which can be temporary or ongoing. This term is commonly used in contexts such as migration, finance (like capital influx), and natural phenomena (like water influx).
The word "influx" comes from the Latin word "influxus," which is the past participle of "influere," meaning "to flow in." The prefix "in-" means "into," while "fluere" means "to flow." The term entered the English language in the early 17th century.
