6. Blank verse
Blank verse forms the basic pattern of language in
Shakespeare's plays. Blank verse in its regular
form is a verse line of ten syllables with five
stresses and no rhyme .
Hence it is called as "blank”. It was first used in
England by Henry Howard, Earl of Surrey in his
translation of the Aeneid (c.1554).

9. Shakespeare's blank verse
In general, Shakespeare's blank verse, and the verse of his peers,
evolved over the years from regular ten-syllable, regular, end-
stopped lines:
(Romeo and Juliet, 2.2.1)

10. Hamlet's most famous soliloquy begins relatively
regularly, but the following lines each have an extra
syllable:

19. Shakespeare's use of blank verse,
or unrhymed iambic pentameter, is
a principal element of his plays. In
rhymed verse, the words that fall at
the end of lines sound very similar,
like "love" and "dove," or "moon"
and "June.“

20. Ye elves of hills, brooks, standing lakes and groves,
And ye that on the sands with printless foot
Do chase the ebbing Neptune, and fly him
When he back; you demi-puppets that
By moonshine do the green sour ringlets make
Whereof the ewe not bites; and you whose pastime
Is to make midnight mushrooms, that rejoice
To hear the solemn curfew; by whose aid,
Weak masters though ye be, I have bedimmed
The noontide sun, called forth the mutinous winds,
And 'twixt the green sea and the azured vault
Set roaring war - to the dread rattling thunder
Have I given fire, and rifted Jove's stout oak
With his own bolt;...
(The Tempest, 5.1)
Shakespeare also used enjambment more often in his verse. His last plays was
given to using feminine endings in which the last syllable of the line is
unstressed. For instance lines 3 and 6 of the following excerpt all of this makes
his later blank verse extremely rich and diverse.

21. But, woe is me, you are so sick of late,
So far from cheer and from your former
state,
That I distrust you. Yet, though I distrust,
Discomfort you, my lord, it nothing
must.
