Primoroso translates to "exquisite" or "lovely." It's a charming and somewhat old-fashioned word that evokes a sense of delicate beauty and meticulous care.
In the song, the lyrics describe "unos ojos tan primorosos" (such exquisite eyes). It's used to emphasize the captivating and beautiful nature of the eyes being sung about, making them sound truly special and enchanting rather than just pretty.
This song, "Hay Unos Ojos" by Gerardo Diaz y su Gerarquia, is all about being completely captivated by someone's eyes! The singer describes how just one look into these eyes makes his "alma tiemble" [soul tremble]. He calls them "tan primorosos, más lindos" [so exquisite, most beautiful], making it clear he's totally smitten.
It's a really passionate declaration, even when others might doubt his feelings. He says, "todos diciendo que no te quiero, que no te adoro" [everyone saying that I don't love you, that I don't adore you], but he begs them, "miente, miente" [lie, lie] because his feelings are so strong. He even says he has "no tengo vida, no tengo miedo" [no life, no fear] without this person, showing just how much these eyes mean to him.
