The Spanish adjective 'toral' comes from combining the Spanish noun 'toro' (meaning 'bull') with the adjective suffix '-al' (meaning 'relating to'). The word 'toro' itself comes from the Latin word 'taurus', also meaning 'bull'. So 'toral' literally means 'relating to or pertaining to bulls'.

The most obvious related Spanish word is 'toro' (bull), which is much more common and fundamental than 'toral'. You might also encounter words like 'torero' (bullfighter) or 'torear' (to bullfight), which are all derived from the same root.

The English word 'taurus' (the astrological sign and constellation) comes from the same Latin root 'taurus'. This connection makes sense since Taurus is represented by the symbol of a bull. The scientific name for cattle species, 'Bos taurus', also preserves this Latin word. We can also see this root in words like 'taurine' (relating to bulls or cattle).
