Effective support for people fleeing the war in Ukraine requires an understanding of their language and communication needs and preferences. Ukraine is multilingual. Ukrainian, the official language, is spoken alongside Russian and minority languages like Romani, Crimean Tatar, Hungarian and Gagauz. Ukrainians affected by the war face multiple language challenges, and barriers to communicating their needs and accessing information and services. The cooperation and involvement of Governments, NGOs and language service providers can all play a vital role in helping Ukrainian refugees to overcome language and communication obstacles, access the information and services they need, and start building their lives in new countries.
