Forms

inonder[1] Old French enunder, enonder; the forms with ⟨i⟩ became general only in the 15th century (1420).[2][3]

Etymology

It is borrowed from Latin inundō (“to overflow, to flood”),[2][3][4][5] formed from in- marking movement towards and undō (“to surge in waves”), itself from unda (“wave”).[2][3][6] The word was first borrowed with the French prefix en-, as Old French enunder and enonder.[2][3]

Compare Italian inondare.[1] Littré cites the Genevan form énondé.[7] French onde goes back to the same Latin noun.[6][3]

Earliest recorded meaning

The first record, enunder in the Oxford Psalter (first half of the 12th century), is intransitive and means “to overflow”, of springs that God made to gush from the rock.[2][7]

Semantic evolution

In the 13th century the intransitive verb was used figuratively of people “flocking in great numbers”.[2][3] The transitive use followed: figuratively “to cover” (about 1250, Robert de Blois), then of water “to cover with water” (about 1265, Brunetto Latini, who says that the Nile floods the land of Egypt).[2][7][3]

By extension the verb was used of tears (1554) and of blood (1653), and figuratively, of people or things, for “to invade, overrun” (1653).[2][3] The past participle became the adjective inondé, used as a noun for a flood victim since 1840.[3] The derivative inondable “liable to flooding” is recorded in 1874.[2][3]
