The Spanish word 'mundial' meaning 'worldwide' or 'global' comes from the Latin word 'mundialis' meaning 'of the world'. This Latin word was formed by combining 'mundus' (meaning 'world') with the suffix '-alis' (meaning 'relating to'). This combination literally meant 'relating to the world', which evolved into the modern Spanish meaning of 'worldwide' or 'global'.

A related and commonly used Spanish word is 'mundo' (meaning 'world'), which comes directly from the same Latin root 'mundus'. You can see how 'mundial' is essentially describing something that relates to 'mundo'.

While English doesn't have a direct cognate of 'mundial', we do use related words borrowed from the same Latin root, such as 'mundane' (originally meaning 'of the world', now meaning 'ordinary' or 'everyday') and 'supermundane' (meaning 'above or beyond the physical world'). The shift from 'of the world' to 'ordinary' in 'mundane' reflects how things of this world were considered common or unremarkable compared to heavenly or spiritual matters.
