This paper examines linguistic insecurity among Filipinos as a hindrance to the progress of Philippine English in Schneider’s Dynamic Model. Using Watts’ sociocognitive approach to language and Rosenberg and Hovland’s (1960) tripartite model of attitude, the connection among language myths in the Philippines, standard-language ideology and prescriptivism is unraveled with the aim of showing that PhE is progressing towards endonormative stabilization. Moreover, this paper introduces the concept of debate tradition, and advances that it is a powerful catalyst in the alteration of linguistic prescriptivism. It is argued that it is necessary to alter the discourse archive of prescriptivism that governs General American English for PhE norm to be completely accepted by Filipinos. To prove diminishing prescriptivism, the change in language attitude towards PhE is shown by comparing surveys. Finally, a graph is presented that clearly shows the weakening of the complaint tradition, which is a strong indicator of endonormative stabilization.
