Blank Verse refers Poetry or prose that does not rhyme but has a consistent meter, usually iambic pentameter.

It has been interpreted as "probably the most common and influential form that English poetry has taken since the 16th century".

Christopher Marlowe was the first English author to attain critical fame for his use of blank verse.

In Shakespeare’s plays, high-born characters usually speak in blank verse, or unrhymed iambic pentameter. Each line consists of ten syllables, which alternate between unstressed and stressed.

But soft! What light through yonder window breaks?
It is the east, and Juliet is the sun.
Arise, fair sun, and kill the envious moon,
Who is already sick and pale with grief,
That thou, her maid, art far more fair than she. (Romeo and Juliet, 2.1.2–6)
