Etymology

Origin of revelation

First recorded in 1350–1400; Middle English revelacion, revelacioun, from Anglo-French revelaciun, revelacioun, revelatiun, from Middle French revelacion, revelation, from Late Latin revēlātiōn- (stem of revēlātiō ), equivalent to Latin revēlā(tus) , past participle of revēlāre “to remove the cover from, unveil, lift the lid of, uncover” + -tiōn- verbal noun suffix dentoting the action of the verb; reveal, -tion; apocalypse ( def. )

Explanation

Discovering that you had a long-lost sister would definitely be a revelation, or a surprising realization. Finding out she had been living in the house next door for years would be an even more startling revelation! It is not a surprise that the word revelation is related to the word reveal, because revealing is the action of showing something that was previously covered up or unknown. You can even use both words in the same sentence: "You might find it a revelation if someone revealed to you that your house was sitting on top of a gold mine!"
