Questions & Answers about El maíz procesado era muy barato.
Where does the word procesado come from, and why does it end in -ado?
It comes from the regular verb procesar (to process). To form the past participle of an -ar verb, you drop the -ar ending and add -ado. In this sentence, it functions as an adjective meaning "processed".
Does procesado change if the noun is plural or feminine?
Why is the verb era used here instead of fue?
Why does maíz have an accent mark on the i?
The accent mark on maíz breaks the vowels into two separate syllables (ma-íz) and tells you to stress the i. Without the accent mark, those two vowels would blend together into a single syllable.
