A metrical foot that takes the following form: unstressed, stressed

"In a summer season when softe was the sonne"

Let us go then, you and I
When the evening is spread out against the sky
Like a patient ethereized upon a table;
Let us go, through certain half-deserted streets,
The muttering retreats
Of restless nights in one-night cheap hotels
And sawdust restaurants with oyster shells:

Some examples of this kind of trope include:

I give you my heart
All hands on deck
Come and rest your bones with me
I got a new set of wheels

"I wandered lonely as a cloud
That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;

The abstract norm of stressed and unstressed syllables that you can scan. It is a measure of emphasis and it creates rhythm.

"Humpty Dumpty sat on a wall,
Humpty Dumpty had a great fall.
All the King's horses, and all the King's men,
Couldn't put Humpty together again"

This is the lower sling swivel. And this
Is the upper sling swivel, whose use you will see,
When you are given your slings. And this is the piling swivel,
Which in your case you have not got. The branches
Hold in the gardens their silent, eloquent gestures,
Which in our case we have not got.

Kenneth Koch uses this literary trope in this line in one of his poems:

I am the evening in which you docked your first kiss

"The whiskey on your breath,
Could make a small boy dizzy;
But I hung on like death:
Such waltzing was not easy"

A metrical foot that takes the following form: stressed, unstressed, unstressed.

"Beside the lake, beneath the trees,
Fluttering and dancing in the breeze"

Seeping past the florist's came the baby and the girl
I am the girl! I am the baby!
I am the florist who is filled with mood!
I am the mood, I am the girl who is inside the baby
For it is a baby girl. I am the old style of life. I am the new

An example of this trope would be the following:

Death has a life
of its own. See
how its album
has grown

"Bats use webby wings that fold up,
Bats from ceilings hang down rolled up;
Bats when flying undismayed are;
Bats are careful; bats use radar"

A part standing in for the whole

"Through granites which titanic wars had groined,
Yet also there encumbered sleepers groaned"

Continuous as the stars that shine
And twinkle on the milky way,
They stretched in never-ending line
Along the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.

In his poem, The Waste Land, Eliot makes use of this literary trope in the first stanza:

April is the cruellest month, breeding
Lilacs out of the dead land, mixing
Memory and desire, stirring
Dull roots with the spring rain...

"For the moon never beams without bringing me dreams,
Of the beautiful Annabell Lee.
And the stars never rise but I feel the bright eyes
Of the beautiful Annabell Lee."

A literary figure in which words, grammatical constructions, or concepts are repeated in reverse order

"A poem should be wordless,
as the flight of birds"

What happens to a dream deferred?
Does it dry up
like a raisin in the sun?
or fester like a sore-
And then run?
Does it stink like rotten mean?
Or crust and sugar over...

This famous line by William Wordsworth uses this kind of literary device:

I wandered lonely as a cloud
That floats on high o'er vales and hills

"Cannon to right of them,
Cannon to left of them,
Cannon in front of them
Volleyed and thundered"
