The Ilocano language is the third largest in the Philippines according to the number of native speakers. Approximately 10 million people speak it around the world.
Like other Philippine languages, it is predominantly Malayo-Polynesian significantly mixed with large Spanish words. Some Chinese and English words were also mixed to which is now the modern Ilocano language.
