The Spanish word 'estor' (meaning 'roller blind') traces its origins back to the Latin word 'storea', which meant 'reed mat'. This evolved into the Italian word 'stora' meaning 'mat', and then into French 'store' meaning 'blind' or 'curtain'. Finally, it was borrowed into Spanish as 'estor', specifically referring to a roller blind. This etymology shows how the meaning evolved from a simple reed mat used as a covering in ancient times to the modern window covering we know today.

While 'estor' is a relatively specific term in Spanish for roller blinds, there don't appear to be any simpler or more common Spanish words that share its etymology.

While the English word 'store' might look similar to 'estor', they are not actually etymologically related. The English 'store' comes from a different Latin root meaning 'to restore, build up'. There don't appear to be any common English words that share the same etymology as the Spanish 'estor'.
