What Is Poetry?
What Makes a Poem a Poem?
An eagle perched on a mountain cliff may attract the attention of a scientist, a traveller, or a poet. Each observes the same bird, yet the descriptions that follow may differ considerably. The difference lies not necessarily in what each person sees, but in the purpose for which the observation is expressed.
Scientific writing seeks to establish facts about the bird. A personal account records an encounter with it. Poetry may begin with the same observable details but arrange them in ways that alter our perception of the subject. These different approaches offer a useful starting point for considering what poetry is and how it works.

The Eagle in an Encyclopedia
An encyclopedia identifies an eagle as a large bird of prey belonging to the family Accipitridae. Eagles generally possess strong hooked beaks, powerful feet, sharp talons, and highly developed eyesight. Different species inhabit forests, grasslands, mountains, and coastal regions, where their physical adaptations enable them to locate and capture prey.
Such a description allows readers to identify the bird and understand its characteristics. The information is organized around features that can be observed, classified, and investigated. The language aims to communicate these features with as little ambiguity as possible.
The eagle's talons, for example, are described in terms of their structure and function. Their strength matters because it helps explain how the bird captures and holds its prey. The description directs attention towards the relationship between a physical characteristic and its biological purpose.
A reader may find this information remarkable. The eagle's eyesight, strength, and capacity for flight can inspire curiosity or admiration. Yet the description does not depend upon producing these responses. Its principal purpose is to communicate knowledge that remains largely unchanged when expressed in different words.
The Eagle in a Personal Account
An encounter with an eagle produces a different kind of description. In Encountering an Eagle, published by WWF Australia, David Waterhouse recounts searching for a golden eagle on Scotland's Isle of Mull. His account follows the experience of observing the landscape, looking for the bird, and eventually seeing it in flight.
"She flapped diagonally along the cliff face, vanishing over the cliff top before serenely rising up above the skyline. She circled briefly on thick, rigid wings, which must have spanned well over six feet. Her projecting primary feathers only added to the impression that we were all staring up at one of those magic flying carpets of Oriental legend."
The subject remains an actual bird in an identifiable location, but the writer's experience now becomes part of the description. The reader encounters the eagle through the observations and expectations of someone who has travelled to see it.
A personal account may include details that would have little place in an encyclopedia: the difficulty of locating the bird, the conditions under which it appears, or the observer's response to its movement. Such details help communicate what the encounter was like rather than merely what kind of creature was observed.
Scientific description and personal observation can therefore share an interest in factual accuracy while differing in emphasis. One explains the characteristics of the eagle; the other places the bird within a particular human experience.
The distinction is not absolute. Scientific writing may contain vivid descriptions, while personal accounts may provide detailed factual information. The two forms nevertheless establish different expectations about what readers will encounter and what they may gain from reading.
The Eagle in Poetry
Consider how Alfred, Lord Tennyson presents the same bird in his six-line poem.

The Eagle
He clasps the crag with crooked hands;
Close to the sun in lonely lands,
Ring'd with the azure world, he stands.
The wrinkled sea beneath him crawls;
He watches from his mountain walls,
And like a thunderbolt he falls.
— Alfred, Lord Tennyson (1809–1892)
The poem presents a recognizable scene. An eagle stands upon a high rock, watches the sea below, and suddenly descends. Nothing in this sequence requires an elaborate narrative. The action could be reported in a single sentence.
Tennyson gives the scene six lines, yet the additional language supplies relatively little factual information. Instead, it determines how the eagle, the landscape, and the movement are perceived.
The opening line establishes an impression that a factual description of the bird's talons would not necessarily produce:
He clasps the crag with crooked hands;
An eagle possesses talons rather than hands. Tennyson's choice of the human term makes the bird's grip resemble a deliberate act. The verb "clasps" strengthens this impression, suggesting that the eagle holds the rock firmly rather than merely rests upon it.
The repeated hard consonants in "clasps," "crag," and "crooked" also give the line a compact, forceful sound. The description works through both the meanings of its words and their audible relationships. The reader encounters not simply the physical position of the bird but an impression of strength created through language.
The following lines establish the eagle's extraordinary height:
Close to the sun in lonely lands, Ring'd with the azure world, he stands.
The phrase "close to the sun" does not provide a measurable altitude. It expresses the bird's elevation through its apparent relationship with the sky. The surrounding blue gives the eagle a commanding presence, while the "lonely lands" suggest its separation from ordinary human activity.
The perspective changes in the second stanza:
The wrinkled sea beneath him crawls;
The sea is ordinarily associated with considerable size and movement. Seen from the eagle's height, its surface appears reduced to wrinkles, while its motion becomes a crawl. The immense body of water seems diminished because the perspective has changed.
The poem concludes with a sudden descent:
And like a thunderbolt he falls.
The comparison suggests speed and force, but its effect depends upon the preceding lines. The eagle has remained almost motionless above a landscape whose movements appear slow and distant. The final line replaces this stillness with an abrupt downward movement.
The order of the images matters. Had the poem begun with the eagle falling, the movement would not have emerged from the same experience of height and stillness. The descent acquires much of its force from its position at the end.
Tennyson's description reveals something about poetic language. The individual words contribute to the impression of the eagle, but their arrangement determines how that impression develops. Sound, imagery, perspective, and sequence work together to shape the reader's experience.
The Importance of Form
The six lines of The Eagle are divided into two groups of three lines. Each group is called a stanza. Just as paragraphs organize ideas in prose, stanzas help organize the language and movement of a poem.
The lines within each stanza also share a pattern of sound. The words hands, lands, and stands have similar ending sounds. This correspondence is called rhyme. In the second stanza, crawls, walls, and falls create another set of rhymes. The repeated sounds give each stanza a sense of unity.
The division into stanzas also reflects a change in the scene. The first stanza presents the eagle standing high above the landscape. The second turns our attention to the sea below before describing the bird's sudden descent. The arrangement of the lines therefore helps organize what the reader sees.
Poetry also has rhythm, a pattern created partly by the arrangement of stressed and unstressed syllables. In ordinary speech, some syllables receive greater emphasis than others. Poets can arrange these stresses to produce a recurring beat called metre. Tennyson's lines have a strong rhythm, although the stresses do not follow an identical pattern throughout.
Together, these features contribute to the poem's form: the way its lines, stanzas, sounds, and rhythms are organized. Form is not merely a decorative feature of poetry. It influences how readers experience the subject. In The Eagle, the arrangement of the lines and the recurrence of sounds help shape our perception of the bird and its movement.
Not every poem, however, depends on rhyme or a regular rhythm. Some poets create their effects through different arrangements of language. To understand the possibilities of poetry, we must also consider poems that do not follow these familiar patterns.
Poetry Beyond Rhyme
Walt Whitman's Song of Myself, first published in 1855, begins with three lines:
I celebrate myself, and sing myself And what I assume you shall assume, For every atom belonging to me as good belongs to you.
Whitman's opening differs considerably from Tennyson's. The lines do not rhyme, and their lengths are unequal. Their movement resembles an expansive declaration rather than the compact, regularly patterned description of an eagle.
The absence of rhyme does not mean that the language lacks organization. The repetition of "myself" establishes the speaker's presence, while the repeated structure of "I" and "you" creates a relationship between speaker and reader.
The movement of thought is equally significant. The speaker begins by celebrating himself, but the declaration soon extends beyond the individual. What belongs to him also belongs to the person he addresses. The reference to "every atom" suggests a connection that reaches beneath the visible differences between people.
Whitman's lines acquire their force through repetition, parallel structure, and the gradual expansion of an idea. Their rhythm develops through the movement of the sentence rather than through a fixed pattern of metre and rhyme.
This kind of writing is commonly described as free verse. The term refers to poetry that does not follow a regular metrical pattern or prescribed rhyme scheme. Freedom from these conventions does not mean freedom from form. The poet must still decide how language moves, where lines end, and how words and ideas relate to one another.
Tennyson and Whitman organize language differently, but both make the manner of expression essential to what readers experience. Their contrast suggests that poetry cannot be adequately defined by the presence of a single formal feature.
The Possibilities of Poetic Language
The comparison also raises a question about figurative language. Tennyson describes the eagle's talons as "hands" and compares its descent to a thunderbolt. Whitman uses the atom to suggest a connection between individuals. Such choices allow words to carry meanings beyond their most immediate reference.
Yet figurative language is not confined to poetry. Ordinary conversation, journalism, and scientific explanation frequently employ metaphors and comparisons. A scientist may use the image of a branching tree to explain evolutionary relationships. A journalist may describe an economic crisis as a storm. In both cases, figurative language helps readers understand an idea by relating it to something more familiar.
The presence of metaphor, therefore, does not by itself make a passage poetic. Nor can poetry be defined entirely by rhyme, rhythm, or the arrangement of lines. These features are important, but none belongs exclusively to poetry, and no single feature appears in every poem.
What distinguishes poetry is better understood through the particular attention it gives to language. In a poem, the choice of a word, the sound of a phrase, the length of a line, or the position of a pause may contribute significantly to the meaning. These elements do not merely communicate an experience; they help determine the character of that experience.
Tennyson and Whitman demonstrate how differently this can be accomplished. Tennyson concentrates a dramatic scene into six carefully patterned lines. Whitman allows his thought to unfold through longer, more expansive lines, without relying on conventional rhyme. Their methods differ, but in both poems the arrangement of language is inseparable from what the poet wishes to express.
Poetry, then, cannot be reduced to a collection of literary devices or formal rules. It is a way of using language in which meaning emerges not only from what is said but also from how it is said. Learning to read poetry begins with attending to that relationship.
Putting Your Reading into Practice
Poetry rewards careful attention to language. Before moving on, return to Tennyson's The Eagle or Whitman's Song of Myself and consider how the poet's choices influence your understanding.
1. Notice the language
Choose one line that interests you. Identify a particular word, image, or sound that makes the line memorable. What do you notice about the poet's choice of language?
2. Consider the effect
Imagine that the poet had expressed the same idea in ordinary prose. What might be lost or changed? Consider the meaning, sound, or impression created by the original wording.
3. Write a short response
In approximately 100–150 words, explain how one feature of the poem contributes to its meaning or effect. Support your interpretation with a quotation and explain how the language produces the effect you have identified.
As you write: Avoid simply naming literary devices. Your aim is to explain what the poet's language accomplishes and why it matters.
