Origin of explanation

First recorded in 1350–1400; Middle English explanacioun, from Latin explānātiōn-, stem of explānātiō, from explānāt(us) “made understandable” (past participle of explānāre “to smooth out, make understandable”) + -iō -ion; see explain

Explanation

An explanation is a statement about how or why something is the way it is. If you're failing math, you'd better come up with a good explanation to give to your parents. Explanation is from the same Latin word as explain: explanare, which means make clear. Because explanation and explain are so closely related, people often try to shoehorn an extra i into the spelling of explanation. Don't. You might think that explanation has the odd spelling, but it is really the more regular of the two because there is no i in explanare.
