The phrase "in flood" does not have a distinct etymology of its own. It is a combination of the word "in" and the noun "flood". However, we can explore the origins of the word "flood" for a better understanding.
The word "flood" originated from the Old English "flōd", which referred to a flowing or overflowing of water, specifically in the context of a large body of water rising above its normal levels and submerging land. The Old English term traces back to the Proto-Germanic word "*flōduz", which had a similar meaning.
It is important to note that the concept of a flood is not unique to the English language, and similar words exist across various Indo-European languages. For instance, Old Norse had "floið" and Old High German had "fluot", both of which signified flood or overflow.
