For example, ‘Mirrored images reflect images mirrored’ which includes a word in the center as a reversal point for the sentence or even the poem.

10.  Cascade – Cascade, a form created by Udit Bhatia, is all about receptiveness, but in a smooth cascading way like a waterfall. The poem does not have any rhyme scheme; therefore, the layout is simple. Say the first verse has three lines. Line one of verse one becomes the last line of verse two. To follow in suit, the second line of verse one becomes the last line of verse three. The third line of verse one now becomes the last line of verse four, the last stanza of the poem. See the structure example below:
    a/b/c,
    d/e/A,
    f/g/B,
    h/i/C
    To make the Cascade an even longer poem, use more lines in verse one. For example, if verse one has 6 lines, the poem must have seven stanzas so that each line of verse one is reused as a refrain in each following stanza (a cascading effect).
11.  Mini-monoverse – The Mini-monoverse is a poetry form originated by Emily Romano. Each Mini-monoverse is made up of two stanzas of five three-syllable lines. They rhyme scheme is a/a/a/a/a for the first stanza and b/b/b/b/b for the second stanza. For a double Mini-monoverse just add two more stanzas. They rhyme scheme for the third stanza should be c/c/c/c/c and for the fourth stanza, d/d/d/d/d. It is desirable that the Mini-monoverse tell a story, but this is not a hard and fast rule.
12.  Pantoum – The pantoum consists of a series of quatrains rhyming ABAB in which the second and fourth lines of a quatrain recur as the first and third lines in the succeeding quatrain; each quatrain introduces a new second rhyme as BCBC, CDCD. The first line of the series recurs as the last line of the closing quatrain, and third line of the poem recurs as the second line of the closing quatrain, rhyming ZAZA. The design is simple:
    Line 1
    Line 2
    Line 3
    Line 4
    Line 5 (repeat of line 2)
    Line 6
    Line 7 (repeat of line 4)
    Line 8
    Continue with as many stanzas as you wish, but the ending stanzathen repeats the second and fourth lines of the previous stanza (as its first and third lines), and also repeats the third line of the first stanza, as its second line, and the first line of the first stanza as its fourth. So the first line of the poem is also the last.Last stanza:Line 2 of previous stanza
    Line 3 of first stanza
    Line 4 of previous stanza
    Line 1 of first stanza
13.  Quinzaine – The English word quinzaine come from the French word qunize, meaning fifteen.

    First stanza, ..1 ..2 ..3 ..4 ..5 ..6
