This study aims to explain the attitude and perception of Sudanese EFL secondary school students towards learning literature to enrich their vocabulary. The study is unique as the researchers believe that no significant research in the undertaken area has been conducted in secondary schools in Sudan. The study sample consists of seventy-nine subjects: thirty girls, thirty-five boys, and fourteen teachers from Ahfad Secondary School in Khartoum. This study investigated vocabulary acquisition challenges faced by secondary school students of Ahfad due to lack of interest, lack of good study material for literature, lack of experienced and well-qualified teachers, lack of modern techniques in the EFL classroom, and the implementation of a designed curriculum. Secondary students can engage in meaningful active communication in English if they have good vocabulary, and literature is the most effective way to expand vocabulary. The study adopted qualitative methodology using a questionnaire and vocabulary building activities to perceive how literature helps vocabulary acquisition. The study results showed that the EFL subjects positively enriched their vocabulary through the existing curriculum. EFL teachers should use innovative methods to inculcate vocabulary acquisition in the heart of the EFL students to develop the spirit of reading sections.
