Mendigar means 'to beg' or 'to plead', a strong Portuguese verb that carries real desperation and vulnerability rather than a simple, casual request. It paints the picture of someone reduced to pleading for something they deserve freely.
Ana Moura sings "Cansada de mendigar" (Tired of begging), expressing exhaustion from having to beg for love or attention that should never need to be earned that way. The weight of the verb turns a short line into a quiet cry for dignity.
Ana Moura casts herself as a beggar in "A Minha Estrela," worn down from asking for nothing more than someone's attention: "Cansada de mendigar / A esmola de um olhar teu" [Tired of begging / For the charity of your gaze]. The star she finds in the sky becomes a stand-in for herself — fixed, distant, and alone — and by the song's close she is still "presa a essa estrela" [bound to that star], "tão sozinha como eu" [as alone as I am]. It's a fado turn on solitude that never resolves into company, only into naming it.
