Annega literally translates to "drowns". It's a strong and evocative verb that isn't commonly found in everyday Italian songs, making it stand out.
In "Rimani Qui", Andrea Bocelli uses it poetically in the line "Su di noi la luce annega le distanze" (Above us the light drowns the distances). Here, "annega" is used metaphorically to suggest that the light is so overwhelming and powerful that it completely engulfs and eliminates any sense of separation or distance, bringing two people closer together.
The song opens on a contradiction: "Canto silenzioso è il mio dolore" (my pain is a silent song). The first verse searches inward rather than outward — "Cerco in me la luce che ha oscurato il mare" (I look inside myself for the light that darkened the sea) — and what the chorus asks for is not an answer but stillness: "Rimani qui / Mio solo amore / Vieni con me / Senza parlare" (Stay here / My only love / Come with me / Without speaking). No talking. Just stay.
The second half brings the same images back changed. Pain stops being sung and starts being remembered — "Muore nel ricordo il mio dolore" (my pain dies in the memory) — and the days deliberately turn ordinary: "Vivo giorni eterni di semplicità" (I live eternal days of simplicity). By the final chorus the distance the sea had swallowed has closed: "Su di noi la luce annega le distanze" (above us the light drowns the distances), "Il mondo esiste dentro noi" (the world exists inside us). The last line is two words, held for almost twelve seconds over the orchestra — "Qui con me" (here with me).
