Etymology

The word 'thirtieth' originates from the Old English 'þrītig' which means thirty, derived from the Proto-Germanic *þrīz and the Proto-Indo-European *treies. The suffix '-eth' is used in forming ordinal numbers in English, derived from the Old English '-eð' which indicates a sequence or order. The construction of ordinal numbers in English can be traced back to the influence of Germanic languages, where similar patterns exist for indicating order. Over time, 'thirtieth' has been consistently used to denote the number thirty's position in a sequence, and it has maintained its relevancy in modern usage across various contexts including mathematics, birthdays, and commemorative events. The cultural significance surrounding the number thirty often highlights milestones in individual lives, such as 'turning thirty,' thus reinforcing its usage in social contexts.
