The Spanish word 'golosina', meaning 'sweet' or 'candy', has its roots in the Latin word 'gula', which meant 'throat' or 'gluttony'. From this came the Latin adjective 'gulosus' meaning 'gluttonous'. This evolved into the Spanish word 'goloso', meaning 'fond of sweets'. Finally, by adding the Spanish suffix '-ina' (which typically forms words for substances), we get 'golosina' - literally something for someone who is fond of sweets, which came to specifically mean candy or sweets in modern Spanish.

A simpler related Spanish word is 'goloso', which means 'having a sweet tooth' or 'fond of sweets'. You can think of 'golosina' as the treat that a 'goloso' person would love to eat!

While not exactly the same, English speakers might recognize a connection to words like 'gullet' (throat) and 'gluttony', which come from the same Latin root 'gula'. Just as these English words relate to eating or the throat, 'golosina' evolved to specifically refer to sweet treats that tempt people who love sweets.
