This is the radical for well — the kind you use to draw up water. Picture an old-timey stone well with wooden posts holding up a crank for reeling up your bucket! Pretty well built, huh?

Well, well… Still can't see it? Try another view: picture a well seen from above. This one's got a square-shaped opening, 'cause that's what Japanese wells used to look like in the old days. Hope this one works well for you!
