民間語源
Folk etymology attributes the name "Bolinao" or this remote fishing enclave from the fish piece "monamon" but commonly called "Bolinao" by the Tagalogs, Bicolanos and the Visayans. A theory also points out that once upon a time "pamulinawen" trees grew luxuriantly along its shores, thus, the Ilocano migrants who crossed the Lingayen Gulf named it phonetically similar to the name of the tree. Nowadays, however, such tree does not exist anymore.
