Inrhetoric,chiasmus (/kaɪˈæzməs/ky-AZ-məs) or, less commonly,chiasm (Latin term from Greekχίασμαchiásma, "crossing", from theGreekχιάζω,chiázō, "to shape like the letterΧ"), is a "reversal of grammatical structures in successive phrases or clauses – but no repetition of words".[1]
A similar device,antimetabole, also involves a reversal of grammatical structures in successive phrases or clauses in an A-B-B-A configuration, but unlike chiasmus, presents a repetition of words.[2]
Chiasmus balances words or phrases with similar, though not identical, meanings:
But O, what damned minutes tells he o'er
Who dotes, yet doubts; suspects, yet strongly loves.— Shakespeare,Othello 3.3
"Dotes" and "strongly loves" share the same meaning and bracket, as do "doubts" and "suspects".
Additional examples of chiasmus:
By day the frolic, and the dance by night.
Despised, if ugly; if she's fair, betrayed.
— Mary Leapor, "Essay on Woman" (1751)[4]
For comparison, the following is considered antimetabole, in which the reversal in structure involves the same words:
Pleasure's a sin, and sometimes sin's a pleasure.
Both chiasmus and antimetabole can be used to reinforceantithesis.[6] In chiasmus, the clauses display invertedparallelism. Chiasmus was particularly popular in the literature of the ancient world, includingHebrew,Greek,Latin andK'iche' Maya,[7] where it was used to articulate the balance of order within the text. Many long and complex chiasmi have been found in Shakespeare[8] and the Greek and Hebrew texts of theBible.[9] Chiasmus is also found throughout theQuran[10] and theBook of Mormon.[11]
Chiasmus can be used in the structure of entire passages to parallel concepts or ideas. This process, termed "conceptual chiasmus", uses a criss-crossingrhetorical structure to cause an overlapping of "intellectual space".[12] Conceptual chiasmus utilizes specificlinguistic choices, oftenmetaphors, to create a connection between two differing disciplines.[12] By employing achiastic structure to a single presented concept, rhetors encourage one area of thought to consider an opposing area's perspective.
Chiasmus derives its effectiveness from its symmetrical structure. The structuralsymmetry of the chiasmus imposes the impression upon the reader or listener that the entire argument has been accounted for.[13] In other words, chiasmus creates only two sides of an argument or idea for the listener to consider, and then leads the listener to favor one side of the argument.
TheWilhelmus, the national anthem of theNetherlands, has a structure composed around a thematic chiasmus: the 15 stanzas of the text are symmetrical, in that verses one and 15 resemble one another in meaning, as do verses two and 14, three and 13, etc., until they converge in the eighth verse, the heart of the song. Written in the 16th century, theWilhelmus originated in the nation's struggle to achieve independence. It tells of theFather of the NationWilliam of Orange who wasstadholder in the Netherlands under theking of Spain. In the first person, as if quoting himself, William speaks to the Dutch people and talks about both the outer conflict – theDutch Revolt – as well as his own, inner struggle: on one hand, he tries to be faithful to the king of Spain,[14] on the other hand, he is above all faithful to his conscience: to serve God and the Dutch people. This is made apparent in the central8th stanza: "OhDavid, thou soughtest shelter from KingSaul's tyranny. Even so I fled this welter". Here the comparison is made between the biblical David and William of Orange as merciful and just leaders who both serve under tyrannic kings. As the merciful David succeeds the unjust Saul and is rewarded by God with the kingdom of Israel, so too, with the help of God, will William be rewarded a kingdom; being either or both the Netherlands, and thekingdom of God.[15]
