Shakespeare has a plethora of words at his disposal, but he chooses to use the word “entertainment”. This is extremely important to the piece as a whole. This phrase is spoken by Lucentio, pretending to be Cambio, to Hortensio, who is pretending to be Litio. The word entertainment means, “an event, performance, or activity designed to entertain others” (Dictionary.com). The connotation of “entertainment” is something to distract people from the real world, which can be music, a play, and a movie. By using the word “entertainment” Lucentio reminds the audience that he is a part of the love triangle (between Bianca, Lucentio and Hortensio,) which is all just part of the grander plot of the play within the play. A few acts have passed since the last interaction between Christopher Sly and the people attending to him , so it is easy to forget that the audience is watching a play within a play. The play within a play starts to get dark and abusive once Petruchio's methods for taming Katherine are revealed, so the reminder of the story not being “real” makes it easier for the audience to digest and sit through.
The use of the word “entertainment” serves as a less severe way of breaking the fourth wall. It doesn’t directly address the audience, as breaking the fourth wall typically does, but it makes the audience aware that the actors know they are performing a play. Shakespeare has utilized breaking the fourth wall in his plays before, so it is interesting that he decides not to in The Taming of the Shrew. One reason for this is so that the impact of the play isn’t completely lost. Shakespeare finds a balance between making the play within a play comical while not getting to harsh.
