Una furtiva lagrima

Una furtiva lagrima (A furtive tear) is the romanza taken from Act II, Scene VIII of the Italian opera, L'elisir d'amore by Gaetano Donizetti. It is sung by Nemorino (tenor) when he finds that the love potion he bought to win his dream lady’s heart, Adina, works.
Nemorino is in love with Adina, but she isn't interested in a relationship with an innocent, rustic man. To win her heart, Nemorino buys a “love potion” with all the money he has in his pocket. The “love potion” is actually a cheap red wine sold by a traveling con man. But when he sees Adina weeping, he knows that she has fallen in love with him and the “Elixir” works.

Translation in English
One furtive secret tear
from her eyes did spring:
as if those youths who can be playful
it ( or she ) seemed to be envious of.
What more searching do I want?
What more searching do I want?
She loves me! Yes, she loves me, I see it. I see it.
Just for an instant the beats
of her beautiful heart if I could feel!
My sighs if they were mingled
for a while with her sighs!
The beats, the beats of her heart if I could feel,
to fuse my sighs with hers...
Heavens! Yes, I could die!
I ask for nothing more, nothing.
Oh, heavens! Yes, I could, I could die!
I ask for nothing more, nothing.
Yes, I could die! Yes, I could die of love.
