What are the oral forms used in the Dilemma Of Ghost?

Ama Ata Aidoo uses a mixture of poetry and prose in Dilemma of a Ghost. Oral form or "speech" reflects social class, age, and background. Eulalie's characters linguistically reflects her background and education. Ato, on the other hand, reflects both his heritage, and his education in his speech, not completely comfortable with either.... he seems stuck inbetween.... something that alienates him from both his family and his wife.
