In the expanded "Indy" lore of 2026, Henry Walton "Indiana" Jones Jr. is confirmed to speak and read at least 27 languages. According to the Young Indiana Jones Chronicles and various tie-in novels, he is fluent in English, French, German, Italian, Spanish, Russian, Swedish, Greek (Ancient and Modern), Latin, Hungarian, Arabic, Turkish, Vietnamese, Thai, Japanese, and several Chinese dialects like Mandarin and Cantonese. He also possesses a deep knowledge of ancient scripts, including Egyptian hieroglyphs, Adamic, and Sanskrit. A famous scene in the television series shows him exhausting a list of European languages while trying to impress a woman, only to be stumped by Welsh. In the 2024 video game The Great Circle, he explicitly mentions knowing 21 languages, though the "Young Indy" series remains the definitive source for his peak polyglot status. This incredible linguistic ability is essentially his "superpower," allowing him to navigate diverse cultures and decipher ancient traps during his global archaeological expeditions.
