tio (Swedish)
Where does "tio" come from?
The Swedish word 'tio' descends from the Old Norse 'tíu', tracing its roots back to the Proto-Germanic '*tehun'. This ancient number ultimately originates from the Proto-Indo-European '*déḱm̥', which remains a foundational term for ten across many modern languages, including English.
