[Question:] When a word DOES describe or refer to an object, is the meaning of that word the same as the object to which it refers?
[Answer:] No. If my only neighbor is the mayor of my town, the phrases “my neighbor” and “my mayor” refer to the same person. Nonetheless, these phrases still have different meanings, because one is used to describe where that person lives (next to me) and the other is used to describe what that person does (the job of mayor). But if two phrases have different meanings but refer to the same object, then their meanings cannot be the same as the object to which they refer.
Would you please explain the bolded? How's it right?
If 'two phrases ... refer to the same object', then they must share AT LEAST ONE mutual meaning, namely the one which refers to the object?
