All that glitters is not gold. The dictionary says that "All that glitters is not gold" means that "Not all the things that glitters are gold", which means that "some of them are gold, and some are not". How strange!! I am puzzled. You see: All that glitters is not gold. Doesn't it deny all the things tht glitters are(?) gold?? Could you please show me how to understand it correctly? Thank you in advance.
