[n] unrhymed verse (usually in iambic pentameter)
A type of poetry, distinguished by having a regular meter, but no rhyme. In English, the meter most commonly used with blank verse has been iambic pentameter. The iambic pentameter form often resembles the rhythms of speech. Verse that does not employ a rhyme scheme. Blank verse, however, is not the same as free verse because it employs a meter e.g. Paradise Lost by John Milton which is written in iambic pentameters.
You stars that reign'd at my nativity,
Whose influence hath alloted death and hell,
Now draw up Faustus like a foggy mist
Into the entrails of yon labouring clouds,
That when they vomit forth into the air,
My limbs may issue from their smoky mouths,
So that my soul may but ascend to Heaven.
