nounUsage in a UPSC answer
The annual inundation of the Brahmaputra valley, while devastating to life and property, simultaneously replenishes the alluvial soils on which the region's agrarian economy depends — a paradox that any disaster-management framework must reconcile.

Root
Latin inundātiō = a flood; inundāre = to overflow; in- = into; unda = wave
Etymology
From Old French inundacion ("flood"), from Latin inundātiō ("a flood"), from inundāre ("to overflow"), from in- ("into, upon") + undāre ("to flow"), from unda ("a wave"); attested in English from the 15th century.
Memory Hook
Latin root unda = 'a wave'; an in-UND-ation is when waves come IN over the land — picture water surging IN and UNDer everything.
How This Word Works in UPSC Writing
The submergence of land under water. It is the more precise word where the fact of submergence matters rather than the flood event itself, which is why inundation mapping is the standard planning tool: it shows which areas go under at which water levels, and therefore what to zone, what to protect and whom to evacuate at each stage of a warning. Coastal inundation from storm surge and sea-level rise is the growing application.
Don’t Confuse It With
Inundation is the state of land being submerged. A flood is the event producing it. Waterlogging is prolonged saturation of soil without necessarily standing water, and damages crops differently. Storm surge is the wind-driven rise in sea level that causes coastal inundation.
Hindi Meaning
जलमग्नता (jalamagnatā) or जलप्लावन.
