Mendriq is one of the Austroasiatic stocks spoken by only 300 people who populated the small part of South East Kelantan. It is an endangered language. These people dwell in an area called Pos Kuala Lah. This article analyses the wh-question words, naken and luk ai, in Mendriq language using the Minimalist framework. These wh-question words will be analyzed using the Minimalist Program to clarify whether the inherent nature of these wh-question words are in situ or moved wh-question words. We found out that the nature of these question words are not influenced by any other words in their respective sentences.Therefore, syntactic analysis will be the best analysis to explain these complex phenomena. Syntactic analysis found out that C (Complementizer) has a strong [uwh] feature but the strength does not require the word to move to the scope position. Instead, this analysis claims that the scope position Spec CP (complementizer phrase) is attended by Op (empty category) in order to check the strong uninterpretive feature (uwh) at C’(komplementizerbar). At the same time, the presence of Op prevents the movement of the question words to the scope position. We hope that this article will contribute to both the theoretical syntax and the preservation of an endangered language.
