Etymology: "Flooder" is a plain formation: the English noun "flood" with the agent suffix "-er," meaning something that performs the action named by the base. Here the base is "flood" used as a verb, so "flooder" describes a thing that causes flooding. The suffix itself has a long pedigree, arriving in English through Middle English "-ere" and Old English "-ere," with a distant ancestry in Latin "-arius," which passed through Old French "-ier" before entering English. The base word "flood" is far older and more rooted. It descends from Old English "flōd," a word for a flowing body of water or the sea's rising tide, which goes back to a Germanic root meaning something like "flowing." Speakers of Old English used the same root for rivers, tides and deluges, and the verb grew out of that noun.
