This idea that language can't be trusted is a major theme in this play, because we initially see how language is used to deceive when Goneril and Regan profess their 'love' to their father. It is interesting to see how this type of language is accepted, while language that is spoken bluntly and truthfully is rejected. Then there is the Fool who plays with language to bring about understanding and this language is accepted.
In conclusion language is an important theme that allows this play to have universality. The way in which each character uses language, allows the reader to see how far a character can go with the words he or she uses. Whether the character is using language to their advantage or if the character is persecuted because of the language they used. Something even more interesting in this play is the fact that the integrity of language is also questioned. Ultimately in this play we see the responses that characters' have toward certain language. We can compare Lear response with the Fool with Lear's response with Kent. This is one of many comparisons that can be made based on the interactions of characters and their response to language.
