Is there a word for when you use an abstract noun in a concrete sense? [closed]

Solution 1:

I would argue that in this metaphor, books weighted with authority, it is not the noun authority that becomes concrete; it is the past participle weighted that becomes abstract, the context simply points to that.

And though a metaphor does many things, it also includes this phenomenon: taking a concrete word and shifting its meaning to something abstract, like a feeling, a concept, etc. OxfordL defines metaphor as:

a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable.

So although a concrete word is not literally applicable to an abstract one, you can do this in a metaphor to obtain new meanings and literary effect:

• His fear consumed him like a hungry beast consumes its prey. (there is no real beast, nor a real prey involved: it is a figure of speech - a metaphor)

Using concrete language can help understand better the abstract meaning we are trying to convey (I recommend this article), but the meaning remains abstract nevertheless.
