This dictionary is a bilingual tool based on theoretical debates and empirical findings, and it aims to gather, in Arabic and English, original multidisciplinary research on gender and sexuality concepts and terms, from a feminist perspective and in a user and reader friendly format. The dictionary looks at the localized usages of the terms and concepts, and it is constituted of 25 entries, organized in alphabetical order with their equivalent and definitions in both Arabic and English. The terms and concepts have been selected based on a series of consultations with gender academics, experts and practitioners as well as activists in Lebanon. They cover established terms and concepts along with emerging ones, in an attempt to highlight the diversity of schools of thought, of paradigms and practices. Each entry or definition proposes a general presentation of the term, a synthetic overview of its inherent debates with a focus on its local usages and understandings.
