abstract words, concrete words

Explanation:

To put it simply , Abstract words consist of something that we can't measure ,  and concrete words consist of something that we can measure

Because of this , abstract words are often used to express things like characteristics or quality, since they are extremely depended on other factors.

For example: This steak tasted marvelous.

The word marvelous over here is considered as abstract. We can't really measure it and there is other chance that other people who taste the steak will have different opinion.

Concrete word on the other hand, is often used for making a generalized facts or scientific statement.

For example: This iron is harder than that sponge.

No matter who tested it, all people will find the same conclusion that iron is indeed harder than a sponge.

one way archaeology us understand the past is through the material objects it finds, allowing us to know what was being used, and when. for example a dig recently found a flute, believed to be the oldest musical instrument found to date.
