The Spanish word 'vendedor' (meaning 'seller') has an interesting Latin origin that combines two concepts. It comes from the Latin word 'venditor' (seller), which itself derives from the verb 'vendere' (to sell). The Latin 'vendere' was formed by combining 'venum' (sale) and 'dare' (to give) - literally meaning 'to give for sale.' Over time, as the word evolved into Spanish, the Latin agent suffix '-tor' became the Spanish '-dor', giving us the modern form 'vendedor'.

Several common Spanish words share this same root. The verb 'vender' (to sell) comes directly from Latin 'vendere'. You might also recognize 'venta' (sale) and 'vendido' (sold). Understanding this family of words can help you remember that 'vendedor' is someone who sells - a seller or salesperson.

While English doesn't have many direct cognates from this Latin root, we do see it in words like 'vend' (as in vending machine), 'vendor' (a seller), and 'vendue' (an auction, though this is archaic). The English word 'vendor' is particularly close to Spanish 'vendedor', as they both derive from Latin 'venditor' and mean the same thing.
