An acrostic is a poem or other word composition in which the first letter (or syllable, or word) of each new line (or paragraph, or other recurring feature in the text) spells out a word, message or the alphabet.^[1] The term comes from the French acrostiche from post-classical Latin acrostichis, from Koine Greek ἀκροστιχίς, from Ancient Greek ἄκρος "highest, topmost" and στίχος "verse".^[2] As a form of constrained writing, an acrostic can be used as a mnemonic device to aid memory retrieval. When the last letter of each new line (or other recurring feature) forms a word it is called a telestich; the combination of an acrostic and a telestich in the same composition is called a double acrostic (e.g. the first-century Latin Sator Square).

Acrostics are common in medieval literature, where they usually serve to highlight the name of the poet or his patron, or to make a prayer to a saint. They are most frequent in verse works but can also appear in prose. The Middle High German poet Rudolf von Ems for example opens all his great works with an acrostic of his name, and his world chronicle marks the beginning of each age with an acrostic of the key figure (Moses, David, etc.). In chronicles, acrostics are common in German and English but rare in other languages.^[3]

Relatively simple acrostics may merely spell out the letters of the alphabet in order; such an acrostic may be called an 'alphabetical acrostic' or abecedarius. These acrostics occur in the first four of the five chapters that make up the Book of Lamentations, in the praise of the good wife in Proverbs 31:10-31, and in Psalms 9-10, 25, 34, 37, 111, 112, 119 and 145 of the Hebrew Bible.^[4] Notable among the acrostic Psalms is the long Psalm 119, which typically is printed in subsections named after the 22 letters of the Hebrew alphabet, each section consisting of 8 verses, each of which begins with the same letter of the alphabet and the entire psalm consisting of 22 x 8 = 176 verses; and Psalm 145, which is recited three times a day in the Jewish services. Some acrostic psalms are technically imperfect. For example, Psalm 9 and Psalm 10 appear to constitute a single acrostic psalm together, but the length assigned to each letter is unequal and five of the 22 letters of the Hebrew alphabet are not represented and the sequence of two letters is reversed. In Psalm 25 one Hebrew letter is not represented, the following letter (Resh) repeated. In Psalm 34 the current final verse, 23, does fit verse 22 in content, but adds an additional line to the poem. In Psalms 37 and 111 the numbering of verses and the division into lines are interfering with each other; as a result in Psalm 37, for the letters Daleth and Kaph there is only one verse, and the letter Ayin is not represented. Psalm 111 and 112 have 22 lines, but 10 verses. Psalm 145 does not represent the letter Nun, having 21 one verses, but one Qumran manuscript of this Psalm does have that missing line, which agrees with the Septuagint. Some, like O Palmer Robertson, see the acrostic Psalms of book 1 and book 5 of Psalms as teaching and memory devices as well as transitions between subjects in the structure of the Psalms. ^[5]

Often the ease of detectability of an acrostic can depend on the intention of its creator. In some cases an author may desire an acrostic to have a better chance of being perceived by an observant reader, such as the acrostic contained in the Hypnerotomachia Poliphili (where the key capital letters are decorated with ornate embellishments). However, acrostics may also be used as a form of steganography, where the author seeks to conceal the message rather than proclaim it. This might be achieved by making the key letters uniform in appearance with the surrounding text, or by aligning the words in such a way that the relationship between the key letters is less obvious. These are referred to as null ciphers in steganography, using the first letter of each word to form a hidden message in an otherwise innocuous text.^[6] Using letters to hide a message, as in acrostic ciphers, was popular during the Renaissance, and could employ various methods of enciphering, such as selecting other letters than initials based on a repeating pattern (equidistant letter sequences), or even concealing the message by starting at the end of the text and working backwards.^[7]

A well-known acrostic in Greek is for the phrase JESUS CHRIST, GOD’S SON, SAVIOUR, the initial letters of which spell ΙΧΘΥΣ (ICHTHYS), which means fish:

Ιησοῦς    I  esoús   Jesus
Χριστός   CH ristós  Christ
Θεοῦ      TH eoú     God's
Υἱός      Y  iós     Son
Σωτήρ     S  otêr    Saviour

According to Cicero, acrostics were a regular feature of Sibylline prophecies (which were written in Greek hexameters. The type of acrostic is that known as a “gamma acrostic” (from the shape of the Greek letter Γ), where the same words are found both horizontally and vertically.^[8] Cicero refers to an acrostic in this passage using the Greek word ἀκροστιχίς.

The 3rd-century BC didactic poet Aratus, who was much admired and imitated by Cicero, Virgil and other Latin writers, appears to have been fond of using acrostics. One example is the famous passage in Phaenomena 783–7 where the word λεπτή 'slender, subtle' occurs as a gamma acrostic and also twice in the text, as well as diagonally in the text and even cryptically taking the initial letters of certain words in lines 2 and 1:^[9]

λεπτὴ μὲν καθαρή τε περὶ τρίτον ἦμαρ ἐοῦσα

εὔδιός κ’ εἴη, λεπτὴ δὲ καὶ εὖ μάλ’ ἐρευθὴς

πνευματίη, παχίων δὲ καὶ ἀμβλείῃσι κεραίαις

τέτρατον ἐκ τριτάτοιο φόως ἀμενηνὸν ἔχουσα

ἢ νότῳ ἄμβλυνται ἢ ὕδατος ἐγγὺς ἐόντος.

leptḕ mèn katharḗ te perì tríton êmar eoûsa

eúdiós k’ eíē, leptḕ dè kaì eû mál’ ereuthḕs

pneumatíē, pakhíōn dè kaì ambleíēisi keraíais

tétraton ek tritátoio phóōs amenēnòn ékhousa

ḕ nótōi ámbluntai ḕ húdatos engùs eóntos.

“If (the moon is) slender and clear about the third day,

she will bode fair weather; if slender and very red,

wind; if the crescent is thickish, with blunted horns,

having a feeble fourth-day light after the third day,

either it is blurred by a southerly or because rain is in the offing.” (trans. Jerzy Danielewicz)

Several acrostics have recently been discovered in Roman poets, especially in Virgil. Among others, in Eclogue 9 the acrostic VNDIS 'in the waves' (lines 34–38) immediately precedes the words quis est nam ludus in undis? 'for what is your game in the waves?'', and DEA DIO (i.e. dea Dione 'the goddess Dione') (lines 46–51) in a passage which mentions the goddess Dione (another name for Venus).^[10] In Eclogue 8, alongside a passage dedicating the poem to an unnamed person and asking him to accept it, Neil Adkin reads the words TV SI ES ACI (i.e. accipe) ('if you are the one, accept!').^[10]

In Aeneid 7.601–4, a passage which mentions Mars and war, describing the custom of opening the gates of the Temple of Janus, the name MARS (the god of war) appears in acrostic form as well as in the text as follows:^[11]

Mos erat Hesperio in Latio, quem protinus urbes

Albanae coluere sacrum, nunc maxima rerum

Roma colit, cum prima movent in proelia Martem,

Sive Getis inferre manu lacrimabile bellum …

“It was a custom in Hesperian Latium, which originally the Alban

cities kept as sacred, and now, greatest of entities,

Rome keeps, whenever they move Mars to the first battles,

whether (they are preparing) to bring tearful war to the Getae …”

In Georgics 1 429–433, next to a passage which contains the words namque is certissimus auctor 'for he is the most certain author', the double-letter reverse acrostic MA VE PV (i.e. Publius Vergilius Maro) is found on alternate lines.^[10]

In Eclogue 6, 13–24 Virgil uses a double acrostic, with the same word LAESIS 'for those who have been harmed' going both upwards and downwards starting from the same letter L in line 19.^[12] Another double acrostic is found in Aeneid 2, where the word PITHI (i.e. πείθει, Greek for he ‘persuades’ or ‘he deceives’) is found first backwards at 103–107, then forwards at 142–146, at the beginning and end of a speech by Sinon persuading the Trojans to bring the wooden horse into the city.^[13] The discoverer of this acrostic, Neil Adkin, points out that the same word πείθει occurs at more or less exactly the same line-numbers in a repeated line describing how Odysseus’ wife Penelope deceived the suitors in Odyssey 2.106 and 24.141.

Another transliterated Greek word used as an acrostic in a pseudo-Sibylline prophecy has recently been noticed in the syllables DE CA TE (i.e. Greek δεκάτη 'tenth') in Eclogue 4, 9–11, with the same DEC A TE repeated cryptically both forwards and backwards in line 11.^[14]

In another pseudo-Sibylline prophecy in poem 5 of Tibullus book 2 the words AVDI ME ‘hear me!’ are picked out in the first letters of alternate lines at the beginning of the prophecy.^[15]

Virgil’s friend Horace also made occasional use of acrostics, but apparently much less than Virgil. Examples are DISCE ‘learn!’ (Odes 1.18.11–15) (forming a gamma acrostic with the word discernunt 'they discern' in line 18) and OTIA 'leisure' in Satires 1.2.7–10, which appears just after Horace has been advised to take a rest from writing satire. The acrostic OTIA also occurs in Ovid, Metamorphoses 15.478–81, a passage describing the return of the peace-loving king Numa Pompilius to Rome.^[16] Odes 4.2, which starts with the word Pindarum '(the poet) Pindar' has next to it the truncated acrostic PIN in a gamma formation.^[17] In the first poem of Horace's Epodes (which were also known as Iambi 'iambics'), the first two lines begin ibis ... amice, and it has been suggested that these words were deliberately chosen so that their initial letters IBI ... AM could be rearranged to read IAMBI.^[18]

Towards the end of the 2nd century AD^[19] a verse-summary of the plot was added to each of the plays of Plautus. Each of these has an acrostic of the name of the play, for example:

Conservam uxorem duo conservi expetunt.

Alium senex allēgat, alium filius.

Senem adiuvat sors: verum decipitur dolis.

Ita ei subicitur pro puella servolus

Nequam, qui dominum mulcat atque vilicum.

Adulescens ducit civem Casinam cognitam.

“Two fellow slaves seek a fellow female slave as a wife;

The old man commissions one of them, his son the other.

A lottery helps the old man; but he is deceived by tricks.

So, instead of the girl, a young slave is substituted,

a naughty one, who beats up the master and the farm-manager.

The young man marries Casina after she is recognised as a citizen.”

The 3rd century AD poet Commodian wrote a series of 80 short poems on Christian themes called Instructiones. Each of these is fully acrostic (with the exception of poem 60, where the initial letters are in alphabetical order), starting with PRAEFATIO ‘preface’ and INDIGNATIO DEI ‘the wrath of God’. The initials of poem 80, read backwards, give COMMODIANUS MENDICUS CHRISTI ‘Commodian, Christ’s beggar’.

Chapters 2–5 of Book 12 in the Right Ginza, a Mandaic text, are acrostic hymns, with each stanza ordered according to a letter of the Mandaic alphabet.^[20]

There is an acrostic secreted in the Dutch national anthem Wilhelmus^[21] (William): the first letters of its fifteen stanzas spell WILLEM VAN NASSOV. This was one of the hereditary titles of William of Orange (William the Silent), who introduces himself in the poem to the Dutch people. This title also returned in the 2010 speech from the throne, during the Dutch State Opening of Parliament, whose first 15 lines also formed WILLEM VAN NASSOV.

Vladimir Nabokov's short story "The Vane Sisters" is known for its acrostic final paragraph, which contains a message from beyond the grave.

In 1829, Edgar Allan Poe wrote an acrostic and simply titled it An Acrostic, possibly dedicated to her cousin Elizabeth Rebecca Herring (though the initials L.E.L. refer to Letitia Elizabeth Landon):

In 1939 Rolfe Humphries received a lifelong ban from contributing to Poetry magazine after he penned and attempted to publish "a poem containing a concealed scurrilous phrase aimed at a well-known person", namely Nicholas Murray Butler. The poem, entitled "An ode for a Phi Beta Kappa affair", was in unrhymed iambic pentameter, contained one classical reference per line, and ran as follows:

Acrostic: Nicholas Murray Butler is a horses ass.

In October 2009, California governor Arnold Schwarzenegger sent a note to assemblyman Tom Ammiano in which the first letters of lines 3-9 spell "Fuck You"; Schwarzenegger claimed that the acrostic message was coincidental, which mathematicians Stephen Devlin and Philip Stark disputed as statistically implausible.^[22][23][24]

In January 2010, Jonathan I. Schwartz, the CEO of Sun Microsystems, sent an email to Sun employees on the completion of the acquisition of Sun by Oracle Corporation. The initial letters of the first seven paragraphs spelled "Beat IBM".^[25]

James May, former presenter on the BBC program Top Gear, was fired from the publication Autocar for spelling out a message using the large red initial at the beginning of each review in the publication's Road Test Yearbook Issue for 1992. Properly punctuated, the message reads: "So you think it's really good, yeah? You should try making the bloody thing up; it's a real pain in the arse."^[26]

In the 2012 third novel of his Caged Flower^[27] series, author Cullman Wallace used acrostics as a plot device. The parents of a protagonist send e-mails where the first letters of the lines reveal their situation in a concealed message.

On 19 August 2017, the members of president Donald Trump's Committee on Arts and Humanities resigned in protest over his response to the Unite the Right rally incident in Charlottesville, Virginia. The members' letter of resignation contained the acrostic "RESIST" formed from the first letter of each paragraph.^[28]

On 23 August 2017, University of California, Berkeley energy professor Daniel Kammen resigned from his position as a State Department science envoy with a resignation letter in which the word "IMPEACH" was spelled out by the first letters of each paragraph.^[29]

In the video game Zork the first letters of sentences in a prayer spelled "Odysseus" which was a possible solution to a Cyclops encounter in another room.^[30]

On 4 May 2024, Noelia Voigt resigned as Miss USA 2023 with a resignation letter containing an acrostic spelling out "I am silenced".^[31]

A double acrostic, may have words at the beginning and end of its lines, as in this example, on the name of Stroud, by Paul Hansford:

 S et among hills in the midst of  five valley S,
 T his peaceful little   market town we inhabi T
 R efuses  (vociferously!) to  be  a  conforme R.
 O nce home  of  the cloth  it gave its name t O,
 U phill and down again its  streets  lead  yo U.
 D espite its faults it leaves  us all  charme D.

The first letters make up the acrostic and the last letters the telestich; in this case they are identical.

Another example of a double acrostic is the first-century Latin Sator Square.^[32]

As well as being a double acrostic, the square contains several palindromes, and it can be read as a 25-letter palindromic sentence (of an obscure meaning).^[33][34]

The poem Behold, O God!, by William Browne,^[35] can be considered a complex kind of acrostic. In the manuscript, some letters are capitalized and written extra-large, non-italic, and in red, and the lines are shifted left or right and internally spaced out as necessary to position the red letters within three crosses that extend through all the lines of the poem. The letters within each cross spell out a verse from the New Testament:

• left: Luke 23:42: "Lord, remember me when thou comest into thy kingdom."
• middle: Matthew 27:46: "O God, my God, why hast thou forsaken me?"
• right: Luke 23:39: "If thou art the Christ, save thyself and us."

The "INRI" at the top of the middle cross stands for Iēsus Nazarēnus, Rēx Iūdaeōrum, Latin for "Jesus of Nazareth, King of the Jews" (John 19:19). The three quotes represent the three figures crucified on Golgotha, as recorded in the gospels of Matthew and Luke.

(The text of the manuscript shown differs significantly from the text usually published, including in the reference.^[35] Many of the lines have somewhat different wording; and while the acrostics are the same as far as they go, the published text is missing the last four lines, truncating the acrostics to "Lord, remember me when thou comest into thy kin", "O God, my God, why hast thou forsak", and "If thou art the Christ, save thyself". The manuscript text is printed below, first as normal poetry, then spaced and bolded to bring out the acrostics. The word "Thou" in line 8 is not visible in this photograph, but is in the published version and is included in a cross-stitch sampler of the poem from 1793.^[36])

                  Behold,  O  God!  IN RI  vers of my tears
               I come to thee! bow         down thy blessed ears
                To hear my Plaint;         and let thine eyes which keep
                   Continual watch         behold a Sinner weep:
                  Let not,      O GOD my GOD        my Sins, tho' great,

      And th-OU,              my bles-T Redeemer,         SA-viour, God,
