Reseller → It is formed from "re-" (meaning again) and "sell" (from Old English "sellan", meaning to give or hand over). The word "reseller" means someone who sells something again, typically after purchasing it from another source.
Think of someone who 'sells' ('sellan') something 'again' ('re-') — that's why a reseller is someone who sells items that they have already bought.
