困 — enclosure 囗 + tree 木
困 is an associative compound showing a tree (木) confined within an enclosure (囗), suggesting something hemmed in and unable to grow. From this image of restriction came the meanings 'trapped,' 'distressed,' and by extension 'tired' or 'sleepy,' as if one's energy were boxed in.
