Gender-neutral language aims to avoid bias by not differentiating or excluding people based on gender. It involves replacing gender-specific words like "mankind" or gendered titles with gender-inclusive alternatives. Examples include using "humankind" instead of "mankind", or using gender-neutral pronouns like "they" instead of gender-specific ones. The document discusses debates around prescriptive vs. descriptive approaches and examines ways to make writing more inclusive through word choices and constructs.
