Has a dead metaphor ceased to be a metaphor?

Question

In its simplest sense, a metaphor is a figure of speech where, essentially, a simile is ellipted to what is apparently a false statement, but as the intention is to emphasise the similarity rather than deceive, this is an accepted linguistic device.

John Lawler is an expert on pointing out in his invaluable and fascinating contributions the extended metaphors on which a lot of our language is built, such as the container metaphor(s) and up-is-achievement metaphor. In a recent post, he pointed out that 'zenith' is used metaphorically as 'high point [of eg a career]'.

However, Wikipedia has this to say about dead metaphors:

There is debate among literary scholars whether so-called "dead metaphors" are dead or are metaphors. Literary scholar R.W. Gibbs noted that for a metaphor to be dead, it would necessarily lose the metaphorical qualities that it comprises. These qualities, however, still remain. A person can understand the expression "falling head-over-heels in love" even if they have never encountered that variant of the phrase "falling in love."

Analytic philosopher Max Black argued that the dead metaphor should not be considered a metaphor at all, but rather classified as a separate vocabulary item.[2] If the verb "to plough" retained the simple meaning of "to turn up the earth with a plough," then the idea of a car "ploughing through traffic" would clearly be a metaphor. The expression would be a comparison between the motion of the plough cutting through the soil and a car speeding through traffic. In order to understand it, one would need to grasp the comparison. However, "to plough" has taken on an additional meaning of "to move in a fast and uncontrolled manner," and so to say that a car "ploughed through the traffic" is a literal statement. No knowledge of the original metaphorical symbolism is necessary to understanding the statement.

For 'zenith', Elliott Frith found a dictionary definition:

Zenith noun

the strongest or most successful period of time

Should we revise our usage of the word 'metaphor' in such cases?

Answer 1

No, There is no imperative to create a new construct here.

When a metaphor ''loses its metaphorical properties'' due to the demise of colloquial meaning of its components, where the meaning remains we call this an idiom. Where the meaning is lost entirely, we call it a dead metaphor. Both of these descriptions are accurate, depending on the time, place and persons from and to which the phrase is spoken or written.

Also I believe the following phrasing manipulates the outcome of the discussion:

'high point [e.g., of a career]'

The above definition includes his very own implied assumption of "high" being strong or successful! It would be far more accurate to simply use the following phrasing in our definition of the zenith of a career:

'strongest or most successful point [e.g., of a career]'

I believe this is simply a discussion of the difference between metaphor and idiom.

In the case of the phrase "Falling in Love" we're really looking at an idiom. Whether or not a person understands this phrase is a combination of 1) whether they've heard that particular idiom, and 2) whether idiom exists in their native paradigm at all (e.g. certain languages have no idioms, and the concept of idiom can be a challenging new one).

However, this is completely separate from the fact that a limber mind can interpret meaning in places where it has not been literally defined. We call this metaphor.

Answer 2

TL;DR Yes, a dead metaphor has ceased to be a metaphor. It's dead. The point to saying it is a dead metaphor is because it is no longer a metaphor. The metaphorical part of it is gone. The literal meaning is now the new one.

What is a dead metaphor? It's a word or phrase that was at one time being used metaphorically, but now that original meaning is no longer present and the word means only the new thing. To be literal minded, there's no carrying over any more, the carrying over is done, you're on the other side.

For example, 'literally' is a dead metaphor. It used to mean 'as written', but now it means 'without any figurative meaning.' You don't even think of writing at all.

If a word or phrase starts out as literal, then moves on to a metaphor, then moves on to a dead metaphor, the fact that it is called 'dead' implies that it is no longer a metaphor, it no longer has its original literal meaning. The literal meaning is no longer there, the metaphorical meaning is barely there, it is not the new meaning entirely without any hint of the metaphor. The metaphor is gone.

One can extract the original meaning by thinking literally (words can maintain multiple meanings and one can simply switch to the older meaning), or one may need to look at the etymology to see that semantic drift has occurred and the original meaning no longer applies.

Note that, in 'dead metaphor', 'dead' is a dead metaphor; you had no idea that you were not taking it literally as 'heart not beating', just 'it doesn't work that way anymore'.

Also, in 'dead metaphor', 'metaphor' is a dead metaphor. It literally means, by translation (also a metaphor for 'metaphor' and a literal translation of 'metaphor' from Greek roots into Latin ones)... where was I... oh yeah... 'meta' means across, and -fer' means carry or bear, so together 'carrying across' like a bridge, and word meanings aren't literally being carried across.

Also 'dead metaphor' is a dead metaphor. If you've followed this far, a dead metaphor is neither dead nor a metaphor nor a literal dead metaphor. It's something that doesn't mean what it used to mean and you hardly think of what that first meaning was (OK, it mostly depends on dead because it is very 'metaphor'-like).

Follow, root (v3), like, used to, depends, very, all these had different meanings way back when and slowly drifted to take on new metaphorical meanings. To some extent, all words are metaphors.
