Etymology
Origin of explain
First recorded in 1375–1425; late Middle English explanen, from Latin explānāre “to smooth out, make intelligible, spread out on flat surface”; see origin at ex- 1, plane 1
Explanation
To explain something is to define it, show how it works, or just tell what it is. Explaining helps people understand. If you know football really well, then you could probably explain it to a non-fan. Explaining makes things clearer. A lot of teaching is explaining — telling how something works. Also, if you do something wrong, people will ask you to explain your actions. Explaining can help someone "get it" — whatever "it" is.
