Antiheidän

antiheidän is a Finnish neologism that emerged around 2019 and gained traction primarily through social media. It functions as a plural pronoun in the third person, serving as a gender-neutral alternative to existing Finnish pronouns like "hän" (he/she) which is singular. The term is a compound of "anti-" (anti-) and "heidän" (their), suggesting a collective or non-binary identity.

The creation and use of antiheidän are part of a broader linguistic trend in many languages to develop gender-neutral pronouns. In Finnish, while "hän" is already gender-neutral in the singular, the need for a gender-neutral plural pronoun has been articulated by some individuals and communities. Antiheidän is one of several proposed solutions that have circulated within discussions about inclusive language.

While antiheidän has been adopted by some individuals and online communities, it is not yet a formally recognized word in the Finnish language by institutions like the Institute for the Languages of Finland. Its usage remains informal and largely confined to specific social circles. The debate surrounding its adoption reflects ongoing discussions about how language can better represent diverse gender identities and expressions.
