Siya Kolisi is one of the biggest names in world rugby, but the Springboks legend is not actually known by his full first name.

The two-time Rugby World Cup-winning captain has become a household name after leading South Africa to glory in 2019 and 2023.

However, the 35-year-old's full name is Siyamthanda Kolisi.

The name, which means "we love him" in isiXhosa, is often shortened to Siya.

In fact, the South African government used his full name when celebrating the Springboks' historic 2019 World Cup triumph.

Kolisi is far from the only rugby star who goes by a shortened name or nickname.
