憔，本义是人的面部焦黄枯小。人的脸色应该是白里透红的，润泽的，现在变成了“焦黄色”，就如同东西被火烤焦但还没有发黑时的颜色，同时失去了水份，叫枯，瘦了叫小，就是“枯小”，所以，憔指的是人的脸色因为某种不好的原因变成了“焦黄枯小”的颜色与样子。 悴，是指的人“忧愁,悲伤”。 这样一来，就好理解了，憔悴，是指人因为忧愁悲伤而致使自己变成脸色焦黄枯小的样子。然后进一步来描写一个人整体给人带来的“面黄肌瘦，精神不振”的样子。 所以，大多数时候“憔悴”用来描写人的脸色。

When something very bad happened to a guy,the guy was so sad that he didn't want to eat or sleep or go out with his friends.His face looked very sad. so you can see he looked very 憔悴（他看起来很憔悴）。For example,a child died in an accident,his father can't accept the truth and he was so sad that he looked very 憔悴。
