The Spanish word 'sangría' comes from the Latin word 'sanguis' meaning 'blood'. This Latin root evolved into the verb 'sanguinare' meaning 'to bleed', which then developed into the Spanish word 'sangre' (blood). The noun 'sangría' was formed by combining 'sangre' with the Spanish noun suffix '-ía', literally meaning 'bloodletting' - a medical practice that was common in medieval times.

Today, 'sangría' is more commonly known as the name of a popular Spanish alcoholic beverage made with red wine and fruit. This meaning developed because the dark red color of the drink resembles blood, taking its name from the medical procedure.

The most obvious related Spanish word is 'sangre' meaning 'blood', which is much more common and fundamental in Spanish vocabulary. Other related words include 'sangriento' (bloody), 'sangrar' (to bleed), and 'ensangrentado' (bloodstained) - all of which share the same Latin root and maintain a connection to the concept of blood.

Several English words share the same Latin root 'sanguis', including 'sanguine' (originally meaning 'blood-red', now meaning 'optimistic' or 'positive'), 'consanguinity' (blood relationship), and 'sanguinary' (involving bloodshed). The medical term 'sanguineous' (relating to blood) also comes from this Latin root.
