Etymology

Origin of inundate

First recorded in 1615–25; from Latin inundātus, past participle of inundāre “to flood, overflow,” equivalent to in- in- 2 + und(a) “wave” + -ātus -ate 1


Explanation

To inundate means to quickly fill up or overwhelm, just like a flood. Your bathroom could be inundated with water if the pipes burst, and hopefully your inbox is inundated with nice emails on your birthday. Commonly used to refer to a deluge of water, inundate can also refer to an overflow of something less tangible, like information. Right before the holidays, toy stores are often inundated with eager parents scrambling to get the latest action figures and video games.
