Blank verse is the technical name for unrhymed iambic pentameter i.e., verse of five feet
per line, with the stress on the second beat of each foot. It's
one of the most common kinds of verse in English: many passages
of Shakespeare's plays are in blank verse, as is Milton's
Paradise Lost and Wordsworth's Prelude.
Under no circumstances should you confuse blank verse with free verse.
