Wasn’t the complete name something like “Las Islas de Filipinas”?
May I butt in? The Komisyon sa Wikang Filipino proposed to change the spelling of the name of our country to “Filipinas” instead of “Pilipinas”. It would acknowledge the use “f” sound in some local languages and the original Spanish spelling. https://news.abs-cbn.com/nation/06/30/13/language-body-wants-pilipinas-changed-filipinas
