Corroborate is formed from "cor-" (meaning together) and "roborare" (meaning to strengthen). The word describes the act of strengthening or confirming something by providing additional evidence or support.
Think of 'together' ('cor-') making something 'stronger' ('roborare') — that's why corroborate means to confirm or support with evidence.
