What are some interesting and original topics for a thesis in English literature?

1- Both Gabriel Garcia Markez's One Hundred years of Solitude and Ngugi Wa Thinogo's Matigari do have many things in common. Among which, the use of magic realism. However, each of them tends to reach a distinctive purpose.  What is it ? 

2- Comparative study between Tawfik Al-hakim's Sparrow of the East and E.m Foster's Passage to India.

3- The Autobiographical Elements in Joseph Conrad's Heart of Darkness   

There is no end to topics to work on in English literature since now the field is English literatures, that is, literature produced in English language, whether in England, US, France, Germany, Africa, India, The Caribbeans, Latin America, Canada or the Middle East, not just British literature. And with the advent of Critical Theories, the field has grown so vast that one feels one life is not enough to read and explore all that. Studies in Post-colonialism and Postmodernism are trendy as well as interesting. Feminism, Psychoanalysis and Post-structuralism are other interesting theories to critically analyse a text. Critical analysis of texts is the most favoured topic leading to PhD in the academia these days.    

Exploring "sexual duality" in Virginia Woolf's Mrs Dalloway (1925), would be an interesting theme. We can also compare the same theme with D.H.Lawrence's "The Blind Man" (1920). We can also deal feminism in Doris Lessing's The Fifth Child (1988) and compare it with the feminism in Mrs Dalloway

INFLEUNCE OF CULTURE ON VENICULAR LANGUAGES

Shelly and Colleredge in a comparison

First, you need to decide on genre. Are you into Drama, Novel, Poetry or Criticism? Then, you need to finish the pre-thesis part, which is generally academic i.e. credit hours, attending lectures, doing mini research work and the like. Afterwards, you can decide which topic or theme you are going to research. And for an MA thesis I would stick to a thematic study,  more or less, with a minimal technical par to tackle.

All my best,
