enter image description hereI have searched the meaning of "classic" in Cambridge dictionary, but I am not satisfied about its meaning as adjective

What is difference between terms classic and old? As we often use terms like for example classic physics, classic music, etc..

  • 1. Use a dictionary - not a search engine! 2. Tell us what you found and why you are still confused: e.g. someone might be an 'old person' - but would you ever describe them as a 'classic person'?! Voted to close for lack of research. – TrevorD Apr 7 at 16:41

  • Einstein may be old to some people, but I would hesitate to put him in the category of a classical physicist along with Newton. – Cascabel Apr 7 at 16:51

"Classic" generally means "Of the highest class", i.e. something very good and worth noting and preserving.

Many old things are classics, and many classics are old. However this is not because the meanings are related, but due to a cause-and-effect relationship between the two properties.

Many of the very old things we have are classics: This is because things of the highest class are things worth preserving, and have often been preserved, sometimes for thousands of years. Whereas old things which are not of the highest class are not preserved, because they are not worth preserving.
