Infortune translates to "misfortune" or "bad luck." It's a more formal and poetic word than common alternatives, making it stand out in the lyrics.
In the song, Céline Dion sings, "Qu'il n'est pire infortune / Que de ne pas aimer" (That there is no worse misfortune / Than not to love). This powerful statement uses infortune to emphasize the profound sadness and emptiness of a life without love, making it a central theme of the song.
Céline Dion's "Et S'il N'en Restait Q'une (je Serais Celle-là)" is such a beautiful declaration of unwavering, romantic devotion! She's basically saying, if there was only one person left in the world who still believed in true love, who would embrace all its ups and downs, she would be that person.
She talks about being the one to "accepter les larmes" [accept the tears] and "se livrer sans arme / Aux griffes de l'amour" [surrender defenseless / To love's claws]. It's about being brave enough to dream under the moonlight with a lover and even foolishly trace "deux cœurs entrelacés" [two intertwined hearts] in the sand. She'd be the one to follow love to the ends of the earth, no questions asked, because for her, "il n'est pire infortune / Que de ne pas aimer" [there is no worse misfortune / Than not to love]. It's a powerful and really moving commitment to love in its purest, most dramatic form.
