Extirpaste comes from the verb extirpar, which means to 'extirpate' or 'eradicate'. It's a strong, almost surgical word, implying a complete removal or uprooting.
In the song, Fito Páez sings, "La noche en que te conocí / Extirpaste mi mal" (The night I met you / You extirpated my evil). He uses this powerful verb to convey how meeting this person completely removed or cured him of his troubles, making it a memorable and impactful choice.
"Bohemia Internacional" is Fito Páez singing about life on the road with his music, carrying songs from city to city and crossing border after border to share them. He asks how many more deserts of love and how many more cities there still are to cross, treating the touring life itself as a kind of pilgrimage.
The song turns from the road to a love that steadies him through it. He remembers the night he met this person and how the music came to embrace him right when he needed it. Life, he says, put him exactly where he belongs, and he doesn't regret anything that came before.
It closes on a simple, grateful picture of two people sharing one life: her jungle and his own restless spirit, him stirring up storms and her setting them free again.
