Tercets in Poetry: Definitions and Examples
Tercet: Definition
A tercet is a unit of three lines of poetry. It can be a poem unto itself, or it can occur within a larger poem. A tercet may rhyme, but it does not have to. It does not matter if the three lines are metered or not.
Types of Tercet Poems
A tercet stanza is a stanza of three lines that occur within a larger poem.
A tercet poem is a three line poem.
A haiku is a tercet poem. There is no set rhyme scheme in a haiku. A triplet is another type of tercet with the rhyme scheme AAA. This means that the last word of each line rhymes. Both an enclosed and a Sicilian tercet have an ABA rhyme scheme. A villanelle is a poem that consists of five tercets and then one quatrain, which is a stanza of four lines. Finally, a terza rima is a tercet with a more complex rhyme scheme: ABA BCB CDC.
Haiku
A haiku may be the type of tercet most people are familiar with. It is defined by its syllabic structure: 5 7 5. The haiku does not need to rhyme, and it is often about nature. It originated in Japan during the 17th century. All haikus are tercets, as a tercet is a three line unit of poetry. However, not all tercets are haikus, as a haiku has strict syllabic requirements.
Triplet
A triplet is a very specific form of tercet in which each line ends with a rhyming word, giving it an AAA rhyme scheme.
Enclosed Tercet
An enclosed tercet is a tercet with an ABA rhyme scheme. This means that the last word of lines 1 and 3 rhyme, but the last word of line 2 does not.
Sicilian Tercet
A Sicilian tercet is a form of an enclosed tercet. It, too, has the ABA rhyme scheme; however, it has the added requirement of being written in iambic pentameter. In a Sicilian tercet, each line contains ten syllables, in which every other syllable is stressed. In other words, it contains five sets of iambs, or five sets of two beats.
Villanelle
As mentioned previously, a villanelle is a poem with five tercets and one quatrain. In addition to specific line requirements, a villanelle also has a specific rhyme scheme. Each tercet has an ABA rhyme scheme, and the quatrain has an ABAA rhyme scheme. In addition, the first and third lines of the first tercet alternate as the refrain in the other lines.
Terza Rima
A Terza Rima is a complex type of poem with an ABA BCB CDC DED rhyme scheme. It is most often, but not always, written in iambic pentameter; although earlier examples often had lines with eleven syllables. It originated in Italy with Dante Alighieri.

Tercet Examples
Haiku Example
By Matsuo Basho
An old silent pond...
A frog jumps into the pond,
Splash! Silence again.
This example follows the syllabic rule of 5 7 5. It is also about nature, which is a common trait of the haiku.
Triplet Example
“Upon Julia’s Clothes” by Robert Herrick
Whenas in silks my Julia goes,
Then, then, methinks, how sweetly flows
The liquefaction of her clothes.
Next, when I cast mine eyes and see
That brave vibration each way free
O how that glittering taketh me!
In this example of triplets in poetry, we see each stanza is a triplet. Therefore, the above poem has an AAA BBB rhyme scheme.
Enclosed Tercet and Sicilian Tercet Example

“Acquainted with the Night” by Robert Frost
I have been one acquainted with the night.
I have walked out in rain - and back in rain.
I have outwalked the furthest city light.
I have looked down the saddest city lane.
I have passed by the watchman on his beat
And dropped my eyes, unwilling to explain.
I have stood still and stopped the sound of feet
When far away an interrupted cry
Came over houses from another street,
But not to call me back or say good-bye;
And further still at an unearthly height,
O luminary clock against the sky
Proclaimed the time was neither wrong nor right.
I have been one acquainted with the night.
In this poem, we can see that Robert Frost used iambic pentameter. He also used the ABA rhyme scheme. That means this is a Sicilian tercet, which is a specific type of enclosed tercet.
Villanelle Example
“Do Not Go Gentle Into that Good Night” by Dylan Thomas
Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.
Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.
Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.
Wild men who caught and sang the sun in flight.
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.
Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.
And you, my father, there on that sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.
In this poem we can see the classic villanelle style. It contains five tercets with an ABA rhyme scheme and a final quatrain with an ABAA rhyme scheme. Lines one and three (“Do not go gentle into that good night” and “Rage, rage against the dying of the light”) alternate as refrains in the last line of each tercet.
Terza Rima Example
From “Ode to the West Wind” Percy Bysshe Shelley
I
O wild West Wing, thou breath of Autumn’s being,
Thou, from whose unseen presence the leaves dead
Are driven, like ghosts from an enchanter fleeing,
Yellow, and black, and pale, and hectic red,
Pestilence-stricken multitudes: O thou,
Who chariotest to their dark wintry bed
The winged seeds, where they lie cold and low,
Each like a corpse within its grave, until
Thine azure sister of the Spring shall blow
Her clarion o’er the dreaming earth, and fill
(Driving sweet buds like flocks to feed in air)
With living hues and odors plain and hill:
Wild Spirit, which art moving everywhere;
Destroyer and preserver; hear oh hear!
In this example we can see the ABA BCB CDC DED rhyme scheme. It is not written in exact iambic pentameter, but it comes close. There are four other sections with the same structure that come after section I.
Lesson Summary
A tercet refers to a three line stanza of poetry. It can be a stand alone poem (tercet poem) or part of a larger poem (tercet stanza.) Some common types of tercets are the haiku, triplet (AAA rhyme scheme), enclosed tercet (ABA rhyme scheme) , Sicilian tercet (ABA rhyme scheme), villanelle, and terza rima (ABA BCB CDC DED rhyme scheme). Some of these poems require iambic pentameter, whereas others do not. A terza rima is a particularly difficult form of tercet to write because there is a complex rhyme scheme, and the poem must be written in iambic pentameter. A triplet is a bit more simple because all three lines rhyme with each other.
