The song includes a line that has given rise to controversy: "Buenos--Ayres se [o]pone á la frente De los pueblos de la ínclita union". In the manuscript and an early printed song-sheet the word "opone" is used; a slightly later version of the song-sheet correcting obvious errors such as spelling mistakes was issued with the same date of 14 May 1813, but with "opone" changed to "pone". The meaning reverses: "Buenos Aires "opposes" the front of the people of the union" to "Buenos Aires "positions itself at" the front ...". The original "opone" has been interpreted as advancing part of the centralist views in Buenos Aires, but has also been considered a "tragical misprint". In many other lines the anthem goes beyond the Argentine theater of the Spanish American wars of independence and references events in Mexico, Central America, Northern South America, and Upper Peru. The growing ideas of independence are reflected in lines such as "On the surface of the earth rises a glorious new nation, her head is crowned with laurels, and a Lion lies defeated at her feet". This portrays not just Spanish absolutism, but Spain itself, as the enemy.
