以为这个单词是容易猜的。其意思应该是坐在沙发上，深陷其中的意思。或者坐在一个巨大的软软的垫在上陷进去的样子。但是不对。词意更侧重在deep上，和seat关系不大，seat在这个词中只是一个非常象征性的表示。先猜一下词意，然后再查词典，意外可以让我们更容易的记住单词。</br>

Read word and guess the meaning, today's word: deep-seated
I think that it is easy to guess the meaning of this word. The meaning should be like that sitting in a sofa or a huge and soft pad then kind of get stuck there. but it is not correct. the meaning is more about "deep". seat it not a point, it just helps "deep" to describe the meaning symbolically. Please guess the meaning first, then check dictionary, unexpectation can help us to remember words easier.
