This edited book explores the ambiguity and overlap in the usage of terms such as "gender-inclusive", "gender-fair", and "gender-neutral" across various disciplines and languages, aiming to achieve conceptual clarity and advocate for standardisation. The authors examine different aspects of gender-inclusivity in European languages including Dutch, English, French, German, Italian, Polish, Romanian, Spanish, and Swedish. This book will be of interest to students and scholars of fields such as Linguistics, Psychology, Anthropology, and Cultural Studies.
