Were shakespearian plays written in blank verse?

Yes, many of William Shakespeare's plays were written in blank verse. Blank verse is a type of poetry that uses unrhymed iambic pentameter. Iambic pentameter is a meter in which each line consists of ten syllables, with the stressed syllables falling on the first, third, fifth, seventh, and ninth syllables. Blank verse is a common meter in English poetry and drama, and it was particularly popular during the Elizabethan era, when Shakespeare wrote his plays.
