Conditions of Excellent Metaphor: Good Simile, Clarity, and Imaginative Force

1. Technical validity and rhetorical excellence

Metaphor transfers an expression to a new use on the basis of resemblance. Yet identifying a metaphor and finding it rhetorically excellent are different judgments. A nonliteral use can be intelligible but still lack clarity, fitness, or expressive strength.

The excellence of a metaphor depends on how well the resemblance supports presenting the subject in the borrowed image. If that resemblance is strained or its purpose obscure, the figure may lose force even when the speaker's figurative intention can be recovered.

Rhetorical analysis therefore asks two questions: by what mechanism is this metaphor formed, and how effectively does the chosen image express the intended meaning?

2. The governing criterion of good metaphor

بِرِعَايَةِ جِهَاتِ حُسْنِ التَّشْبِيهِ
By observing the features that make a simile effective.

The primary criterion for the excellence of realized and representational metaphor is the quality of the underlying simile. Although the comparison is not overtly stated as a simile, its ground of resemblance still links the intended subject with the borrowed image.

A fine metaphor therefore requires more than an unusual word: it combines a fitting relation, fulfillment of the rhetorical purpose, and an elegant mode of presentation. Difficulty or rarity alone is not proof of beauty.

3. Where excellence lies in realized and representational metaphor

In realized metaphor, one meaning is represented under the expression of another, as when a courageous person is called a lion. A recognizable shared quality must connect the two meanings.

In representational metaphor, a whole situation or expression is transferred to a similar situation. Its quality depends on the fit between the two complete configurations, not simply on the sounds or dictionary meanings of isolated words.

The common test is whether the selected resemblance gives the audience a coherent and purposeful understanding or instead demands strained interpretation.

4. The resemblance must fit both terms

يَكُونُ وَجْهُ الشَّبَهِ شَامِلًا لِلطَّرَفَيْنِ
The ground of resemblance should extend to both sides.

Calling a courageous person a lion works because bravery can serve as a fitting shared quality. If the chosen property has no coherent connection with the familiar image of a lion, the comparison becomes weak.

Shared resemblance does not mean that the subject and the borrowed image are literally identical or alike in every property. It means that the specific feature intended by the expression is relevant to both.

5. The force of the resemblance and the intended purpose

التَّشْبِيهُ وَافِيًا بِإِفَادَةِ مَا عُلِّقَ بِهِ مِنَ الْغَرَضِ
The comparison should adequately convey the purpose assigned to it.

A shared property is not sufficient unless the figure also serves its intended rhetorical goal. A lion may be suitable when the aim is to convey courage, but using the same image to suggest gentleness would normally be a poor fit.

Different intentions can require different borrowed images. The quality of a metaphor must therefore be tested against its subject, context, and purpose rather than the isolated appeal of its wording.

6. Overt comparison versus metaphorical claim

وَأَنْ لَا يُشَمَّ رَائِحَتُهُ لَفْظًا
The wording should not openly disclose the smell of simile.

A metaphor typically presents the subject as though it belongs to the kind represented by the borrowed image. If an explicit comparison is added at the same point, that strong rhetorical claim can be weakened. “Zayd is a lion” and “Zayd is like a lion” are closely related in sense but not identical in rhetorical force.

The condition concerns overt wording that exposes the simile, not the absence of resemblance in thought. Resemblance remains the underlying basis of metaphor.

7. Two expressions of the same intended quality

زَيْدٌ أَسَدٌ
Zayd is a lion.

In an appropriate context, “lion” expresses courage figuratively; the context rules out an actual animal. The person is presented directly under the borrowed image.

زَيْدٌ كَالْأَسَدِ
Zayd is like a lion.

The second formulation contains an explicit comparative particle and openly states a resemblance. The first places greater emphasis on a claimed identity with the image. Both constructions may be meaningful, but they differ in the specific rhetorical effect of metaphor.

8. A resemblance clear in itself

جَلِيًّا بِنَفْسِهِ
Clear without an additional convention.

When the common quality is immediately recognizable, the audience need not solve a puzzle to understand the transferred image. For example, describing a brave person as a lion normally relies on a readily available association with courage.

Clarity is an important condition, but a familiar resemblance is not automatically a brilliant one. The figure should still achieve the particular purpose with force, economy, or vividness rather than merely restate an ordinary comparison.

9. Clarity supplied by common convention

أَوْ بِوَاسِطَةِ عُرْفٍ عَامٍّ
Or through a generally shared convention.

Some resemblances are not equally obvious to all people by direct observation, but are familiar within ordinary linguistic or cultural usage. Such a metaphor can be understood through shared convention, without requiring an elaborate new argument.

Common usage is not merely a dictionary entry; it includes habitual associations between an image and a quality. Those established associations enable listeners to recognize the transferred meaning quickly.

10. Clarity supplied by specialized convention

أَوِ اصْطِلَاحٍ خَاصٍّ
Or through a particular professional or learned convention.

A group trained in a particular discipline may recognize a resemblance immediately even if a general audience does not. For that audience the metaphor can be clear because the specialized association is already understood.

Therefore, rarity alone does not settle the quality of an image. What matters is the intended audience: an expression lucid among specialists can become obscure and ineffective when used without explanation before people outside that tradition.

11. The defect of an obscure riddle

لِئَلَّا تَصِيرَ الْاسْتِعَارَةُ إِلْغَازًا
So that the metaphor does not turn into a riddle.

If the resemblance is neither immediately apparent nor supported by shared custom or the audience's specialized knowledge, the figure can become difficult to interpret. The listener must first invent a link between apparently unrelated things rather than receiving the intended meaning.

Subtlety may be an advantage, but obscurity by itself is not eloquence. Sophisticated meaning should be distinguished from an unintelligible puzzle: a successful image illuminates its purpose instead of hiding it.

12. A concealed resemblance and poor fit

A possible link between two subjects is one thing; a recognizable link that serves the audience and purpose is another. If listeners must invent an extremely remote interpretation, the metaphor may be aesthetically weak.

Obscurity of resemblance does not necessarily mean that the figurative intention is logically impossible. It is primarily an issue of rhetorical quality. An appropriate contextual explanation might make a previously obscure image intelligible.

The practical criterion is that the intended sense should be recoverable by the audience through a fitting relation and context, not locked inside the speaker's private associations.

13. The lion example and an unsuitable intended feature

رَأَيْتُ أَسَدًا
I saw a lion.

If the intended referent is a courageous person, bravery is the familiar resemblance. If the speaker instead means someone with an unpleasant breath and intends that as the resemblance, the connection is not normally obvious to the audience.

The textbook's example of meaning an ill-breathed person illustrates the problem of selecting a feature not customarily associated with the borrowed image. The transfer may be conceived by the speaker, but it does not make an effective metaphor for the audience.

14. An unfamiliar link is not the same as a contextual clue

A listener may readily take “lion” as a figure of courage. To use it for an unusual quality may require additional contextual information, but even an elaborate explanation does not automatically create a fine metaphor.

The ground of resemblance is the quality connecting the two sides; the contextual clue indicates that the literal referent is not meant in this particular use. An unsuitable resemblance and an insufficient clue are separate defects.

Showing that an actual animal is not intended does not, by itself, identify an unexpected feature that the audience has no reason to associate with a lion.

15. Fitness of the complete scene in representational metaphor

A representational metaphor transfers the likeness of a complete scene rather than merely substituting one noun. The borrowed configuration should fit the intended situation as a whole. A superficial match in one detail is inadequate if the essential structure of the situations differs.

The listener should be able to identify what situation is pictured and what comparable pattern occurs in the intended situation.

Word-by-word paraphrase alone will not explain a representational figure; its quality lies in the overall arrangement formed by several linked details.

16. The image of a hundred camels

رَأَيْتُ إِبِلًا مِائَةً لَا تَجِدُ فِيهَا رَاحِلَةً
I saw a hundred camels, yet not one suitable riding camel among them.

The statement depicts a large group in which numbers are plentiful but the desired capability is scarce. When the scene is applied to people, its purpose is no longer an account of animals.

The composite resemblance is the scarcity of a suitably qualified member despite a large population. The camels, the useful mount, and the number together form a scene that can be transferred to a human situation.

17. The explicit simile and its representational reuse

النَّاسُ كَإِبِلٍ مِائَةٍ لَا تَجِدُ فِيهَا رَاحِلَةً
People are like a hundred camels among which a suitable mount is scarcely found.

The particle of comparison makes the simile explicit. If the entire camel scene is then used for a human group without that comparison structure, its rhetorical treatment differs. Ignoring the wording obscures the distinction between simile and representational metaphor.

Both forms communicate the scarcity of the desired quality. One directly states likeness; the other evokes the first scene as an image applied to a new situation.

18. Not every simile is suitable for metaphor

كُلُّ مَا يَتَأَتَّى فِيهِ الِاسْتِعَارَةُ يَتَأَتَّى فِيهِ التَّشْبِيهُ مِنْ غَيْرِ عَكْسٍ
Where metaphor can be made, simile is possible; the reverse does not necessarily hold.

An explicit comparison can register a limited likeness even when the subject cannot convincingly be treated as belonging to the very kind represented by the image. Metaphor makes the stronger rhetorical claim by suppressing open comparison.

This principle concerns the effectiveness of metaphor. Deleting a comparative particle from any possible simile does not automatically yield a strong, successful metaphor.

19. A proper balance between obviousness and remoteness

The resemblance should neither be an empty cliché nor so remote that the listener has no route to understanding it. The beauty of metaphor often lies in balancing intelligibility with imaginative force.

A distant resemblance can stimulate thought in an explicit simile. Metaphor, however, goes further by speaking of the subject through the borrowed image itself. The most useful novelty is one that advances understanding rather than burying it.

Rhetorical excellence depends on audience and occasion. A connection obvious to one circle can require explanation for another, so the context of communication matters.

20. A powerful resemblance approaching claimed identity

إِذَا قَوِيَ الشَّبَهُ بَيْنَ الطَّرَفَيْنِ حَتَّى اتَّحَدَا
When resemblance between the two sides becomes so strong that they seem united.

This does not assert actual identity. The association can become so strong in expression that repeatedly restating the comparison seems unnecessary. Metaphor can then express the recognized relation with greater compression and a stronger rhetorical claim.

The unity is restricted to the specific intended aspect. The objects remain distinct in reality even when the speaker presents them as nearly indistinguishable in that respect.

21. Knowledge and light as a strongly associated pair

Knowledge dispels the darkness of ignorance, while light removes physical darkness. The two are associated through an intelligible effect that listeners can readily grasp. Calling knowledge “light” therefore presents its benefit in a perceptible image rather than giving a new dictionary definition.

Where the two concepts are especially close in the intended effect, direct metaphor can carry greater emphasis than merely saying “knowledge is like light.”

The resemblance does not make the concepts identical in nature; it points to their shared power to disclose and clarify.

22. The expressive force of “light entered my heart”

حَصَلَ فِي قَلْبِي نُورٌ
A light arose in my heart.

If the context concerns gaining knowledge or understanding, the expression depicts inward comprehension through the sensory image of light. An abstract intellectual state becomes vivid and immediate.

By contrast, “knowledge is like light” openly declares resemblance. The two formulations differ in structure and force: the first pictures light arising in the heart, while the second merely compares knowledge to light.

23. Doubt and darkness: a matching pair

وَقَعْتُ فِي ظُلْمَةٍ
I fell into darkness.

When the context concerns uncertainty, doubt, or confusion, physical darkness can represent intellectual disorientation or lack of clarity. It parallels the relation between light and knowledge.

فِي شُبْهَةٍ كَالظُّلْمَةِ
In a doubt resembling darkness.

The second phrasing openly states a simile; the first may use darkness metaphorically. The difference is not just the number of words, but whether the image is made directly present or explicitly compared.

24. Excellence in implicit metaphor

وَالِاسْتِعَارَةُ الْمَكْنِيُّ عَنْهَا كَالتَّحْقِيقِيَّةِ فِي أَنَّ حُسْنَهَا بِرِعَايَةِ جِهَاتِ حُسْنِ التَّشْبِيهِ
Implicit metaphor, like realized metaphor, is excellent through observing the qualities of a sound comparison.

In implicit metaphor the intended subject remains stated, while an attribute associated with the comparison image points to the concealed likeness. An unusual attribute alone cannot make the image beautiful if the underlying resemblance is unconvincing.

For instance, claws associated with death are powerful only when death's grip can suitably be connected with a predator's power to seize or tear.

25. The dependent quality of imaginative metaphor

وَالِاسْتِعَارَةُ التَّخْيِيلِيَّةُ حُسْنُهَا بِحَسَبِ حُسْنِ الْمَكْنِيِّ عَنْهَا
The beauty of imaginative metaphor depends on that of its associated implicit metaphor.

An imagined attribute ascribed to the subject depends on the hidden comparison that makes its attribution meaningful. If the basic likeness is unsuitable, its added imaginative feature does not become eloquent merely because it is striking.

The underlying comparison must therefore be assessed first; then one asks whether the associated imaginative details strengthen the image or turn it into forced ornament.

26. Two levels of quality in “the claws of death”

أَظْفَارُ الْمَنِيَّةِ
The claws of death.

First level: death is implicitly related to a predator through overpowering, seizing, and harming. This is the basis of the hidden comparison. Without that link, attributing claws would be arbitrary.

Second level: the imagined claws intensify the felt grip and terror of death. Their effectiveness depends on the first comparison; they make the relationship more vivid rather than create a separate, self-sufficient source of eloquence.

The figure's quality rests on both the basic resemblance and the supporting imaginative detail.

27. A comparative table of four metaphorical forms

The conditions of excellence are not identified by one surface feature across all forms. Their underlying likeness, transferred meaning, and means of representation must be considered separately.

FormPrimary test of excellence
RealizedAppropriate shared quality and avoidance of overt simile
RepresentationalFitness of the two complete scenes and achievement of purpose
ImplicitAppropriate hidden comparison and its associated feature
ImaginativeFitness of the supporting image and the implicit metaphor it accompanies

This classification shows why identifying a technical label is not enough: evaluation requires examining whether the actual image performs its intended rhetorical task well.

28. A practical method for evaluating a metaphor

Before evaluating the excellence of a metaphor, identify its working elements.

1. Determine the subject and comparison image, or the two complete situations.
2. Identify a resemblance fitting both sides and the communicative purpose.
3. Check that the audience can grasp the link directly or through a shared or specialist convention.
4. If the direct metaphorical claim is intended, make sure the wording has not collapsed back into overt simile.
5. See whether imaginative details strengthen the basic image rather than replace it.

These tests distinguish technical classification from expressive success, making evaluation reasoned rather than impressionistic.

29. Synthesis: metaphor and the goodness of its comparison

The central criterion of excellent metaphor is the quality of the underlying comparison. Its resemblance must fit the intended subject and borrowed image, advance the speaker's purpose, and remain intelligible to the audience. The connection may be directly clear, commonly understood, or recognized within a specialist convention.

In realized and representational metaphor, avoiding overt simile preserves the force of the metaphorical claim. Where two ideas are strongly associated in one respect, direct metaphor may offer greater emphasis and economy than explicit comparison.

Implicit metaphor depends on the fitness of its concealed likeness, while imaginative metaphor depends on the quality of that underlying image. Successful metaphor thus requires more than unusual wording: it needs attention to meaning, relation, and audience.
