This paper aims to define the concept and function of feminist literature written in the Spanish and Arabic languages through a comparative inferential approach. Moreover, it deals with the points of view presented by critics about the origin of the name of this literary genre. Further, the study attempts to clarify the doubts that usually accompany reading or hearing the term "feminist literature" by illuminating the origin of the term, the existence of non-feminist literature and the classification criteria in Spanish and Arabic feminist literature. Comparing the assumptions of Spanish critics and writers with their Arab counterparts led to the conclusion that there are three terms that should be conceptualized and defined: “feminist literature", “women's literature" and “literature written by women." Additionally, from a literary perspective, genres should not be classified on the basis of the author's gender, because the term “feminist literature" would serve, conversely, as a kind of audience guidance that would make this type of writing unacceptable to a stratum of readers. It should be noted that when literary criticism is directed towards a political or ideological movement (as the case of feminism), it pays more attention to the stereotypical and cultural image of women without worrying about the aesthetic value of the artwork.
