Etymology of "Understand"

[mandyjw]

 

"Etymology's joke on us is that our very words that mean "grasp an idea of, mentally fit together parts of reality" — are themselves obscure or incomprehensible to us.

Understand is so plainly odd that even people who don't think about word histories notice it. In form it is a compound of under + stand (v.), and it has been so since Old English. Likewise the sense has not shifted since King Alfred's day: "to comprehend, grasp the idea of, receive from a word or words or from a sign the idea it is intended to convey; to view in a certain way."
