Breakdown:
* Anne: This is a contraction of the word "ennu" (meaning "is it" or "is it that") and "ne" (meaning "you").
* Thirakkiyo: This is the past tense of the verb "thirakkuka," which means "to open."
Therefore, "anne thirakkiyo" literally translates to "Is it that you opened it?", which is grammatically simplified to "Did you open it?" in English.
