      Tamás is the Hungarian form of Thomas, a name with ancient Aramaic origins meaning "twin." Pronounced "TAH-mahsh," it features prominently in Hungarian culture and history, including notable bearers like Hungarian composer Tamás Vásáry. The name has been consistently popular in Hungary throughout the centuries and remains a common choice for Hungarian families today. While maintaining strong cultural roots in Hungary, it has limited international recognition beyond Central Europe. The distinctive accent mark over the 'a' (the acute accent) indicates the long vowel sound in Hungarian pronunciation. For Hungarian diaspora communities, choosing this name often represents a way to connect children with their cultural heritage while offering a name that balances uniqueness outside Hungary with traditional significance within it.
