Shaw was very concerned with the state of the English language, particularly its spelling, punctuation and pronunciation. He campaigned for the simplification of the written language. He said english have no respect fpr their language, and will not teach their children to speak it. They cannot spell it because they have nothing to spell it with. Professor Higgins, the famous phonetician, despises the morals of the social class to which he belongs., yet he also despites the lower classes, although he recognizes their natural inteligence. The main hereo´s name is Eliza a flowergirl selling flowers in covent garden of no education and of very low background, becomes his pupil and with Higgin´s help and the challenge of colonel Pickering´s bet she achieves such excellent pronunciation and behaviour that at a ball she is taken for a duchess. Higgins, who does not realize what problem lie ahead for Eliza in her new situation, does not bother about what will become of her. Eliza however is not willing to suffer being somebody´s plaything. Higgins knows he will does not decide the final solution between Higgins and Eliza, yet in his own epilogue to the play he says quite clearly that the two characters could no longer live together because both are too independent..
