Social Class and Status
In A Midsummer Night's Dream, the social class and status of characters are indicated by the language they employ. Theseus and Hippolyta, most noble of the mortal cast, use blank verse throughout, as do Oberon and Titania. The mechanicals, rough, working men, use prose in all their scenes.
Where the Mechanicals do employ verse, in their play within a play, it is mock heroic doggerel, with overconvoluted rhymes. This reinforces the idea that the men are acting outside their social class.
The lovers use rhyming couplets in many of their scenes. This reinforces their social status, but also conveys a sense of urgency to their speech, keeping the action moving swiftly onwards.
