The Spanish verb 'rebatir' (meaning 'to refute' or 'to counter') comes from combining two Latin elements: the prefix 're-' meaning 'again' or 'back', and the verb 'battuere' meaning 'to beat' or 'strike'. The Latin 'battuere' first evolved into the Spanish verb 'batir' (to beat), and then the addition of 're-' created 'rebatir', giving it the metaphorical sense of 'beating back' an argument or claim - hence its modern meaning of refuting or countering.

A simpler and more common Spanish word that shares this etymology is 'batir', which means 'to beat' or 'to whisk'. While 'batir' retained the literal physical meaning of beating or striking from Latin 'battuere', 'rebatir' developed a more abstract meaning of countering arguments. You might find it helpful to think of 'rebatir' as mentally 'beating back' someone's arguments.

Several English words are related to 'rebatir' through the Latin root 'battuere', including 'battle', 'combat', 'debate', and 'rebate'. 'Battle' and 'combat' preserve the notion of physical fighting or striking, while 'debate' (like Spanish 'rebatir') took on a more intellectual meaning of verbal argument or discussion. 'Rebate' followed a different semantic path to mean 'beating back' or reducing a price.
