The word "thirty" can be traced back to the Old English word "þritig", which was derived from the Proto-Germanic word "*thritigō". This can be further traced to the Proto-Indo-European root "*tréyes" meaning "three". The suffix "-ty" is a common English adjectival suffix added to numerical bases to form multiples of ten, which is why "thirty" means three tens or three times ten.
