What does "influx" mean?

Influx: A coming in; infusion; intromission; introduction; importation in abundance; also, that which flows or comes in; as, a great influx of goods into a country, or an influx of gold and silver. The influx of food into the Celtic region, however, was far from keeping pace with the influx of consumers. Macaulau. The general influx of Greek into modern languages. Earle.
