I guess "meaning" is one of the most commonly used words on this site. However, I am not sure whether I understand and use it correctly.
Cambridge Dictionary gives this definition about "meaning"
The meaning of something is what it expresses or represents
and gives this example
The word "flight" has two different meanings: a plane journey, and the act of running away.
which means that, a word could have multiple meanings.
so far so good.
An ELL post says
I think the two sentences have identical meanings.
I understand the sentence conveys that those two sentences mean the same thing. I don't understand why do there exist two identical meanings. Provided two sentences mean the same thing, there should be only one meaning. What am I missing? Could someone please give a hint? Thanks in advance.
