The Spanish word 'calderón' meaning 'large cauldron' has its roots in Latin. It starts with the Latin word 'calidus' meaning 'warm' or 'hot'. This evolved into the Latin term 'caldaria', which referred to a 'hot water vessel'. The word then developed into the Spanish 'caldera' meaning 'cauldron'. Finally, by adding the Spanish augmentative suffix '-ón' (which makes things bigger), we get 'calderón' - literally meaning 'large cauldron'.

A simpler and more common related Spanish word is 'caldera', meaning 'cauldron' or 'boiler'. This is essentially the same word as 'calderón' but without the augmentative suffix. You might also encounter words like 'caldero' (cooking pot) in the same word family. These all share the connection to heat and cooking vessels from their Latin origins.

English speakers might recognize the connection to words like 'cauldron' and 'caldron', which share the same Latin ancestry through 'caldaria'. The connection between these words is quite clear, as they all refer to large vessels used for heating or cooking. Another related English word is 'caldera', which is actually borrowed from Spanish and refers to a large crater formed by volcanic activity - maintaining the connection to heat from the original Latin 'calidus'.
