The Spanish word 'loroco' refers to edible flower buds that are commonly used in Central American cuisine, particularly in El Salvador. The exact etymology of this word is unclear, but it likely originates from an indigenous language of Central America, possibly from one of the native languages of El Salvador or Guatemala where the plant is widely cultivated and consumed.

Given that 'loroco' appears to be borrowed from an indigenous language, there are no simpler or more common Spanish words that share its etymology.

There are no etymologically related English words to 'loroco', as it comes from an indigenous American source. In English, the plant is simply called by its Spanish name 'loroco' or sometimes described as 'Fernaldia pandurata', its scientific name.
