The Spanish word 'chompa', meaning 'sweater' or 'long-sleeved shirt', has an interesting journey through multiple languages. It ultimately comes from the Arabic word 'jubba', which referred to a long outer garment. This word made its way into Old French as 'jupe', meaning 'leather jacket'. The word then entered English as 'jump', referring to a short coat, and later evolved into 'jumper' specifically meaning a sailor's jacket. Finally, the word was borrowed into Spanish as 'chompa', with its current meaning of a sweater or long-sleeved shirt. You can see how the meaning has stayed within the realm of clothing while gradually shifting from long outer garments to more specific types of upper body wear.

While 'chompa' is primarily used in some Latin American varieties of Spanish, it doesn't have many common related words in Spanish itself, as it entered the language relatively recently through English.

English speakers might recognize the connection between 'chompa' and the English word 'jumper', which in British English refers to what Americans call a sweater. The English words 'jump' (as in a short jacket) and 'jumper' are direct relatives of 'chompa', though these clothing-related meanings of 'jump' are now somewhat archaic in English. This connection can help English speakers remember that 'chompa' refers to an upper body garment.
