This paper delves into the morphological features of Siquijodnon-Cebuano language. Using descriptive research methodology and adapting the linguistic theory, Contextualisation Lexicalisation, the study broadly examines free morphemes, bound morphemes and other morphological features of the Siquijodnon language. Qualitative data were taken from written folk literary works, documentaries, transcripts and oral traditions of selected Siquijodnon folks/informants who were chosen through convenient purposive sampling. They were gathered through snowball and/or Participatory Rapid Rural Appraisal (PRRA), interview and videotaping. The units of analysis include the linguistic morphological features: free morphemes, bound morphemes and other morphological phenomena of a language. The data were analysed in the framework of Congruent Lexicalisation and interpreted through interpretive analysis. The research instrument is an interview guide. Considering the aforementioned findings, it is concluded that Siquijodnon-Cebuano is a rule-governed language, which certainly shares a number of morphological features with English and other prevalent languages or dialects. The results also manifest the essential contribution of affixation in establishing inflectional bound tense-marking morphemes and derivational bound from class-marking morphemes. They further conclude that Siquijodnon encounters with other language speakers, brought about by colonisation, greatly influenced the morphological development of their language. Hence, the Siquijodnon language is a twinskin of Siquijor Island's local identity, which likewise holds a utilitarian significance for its folk literary, historical, cultural and socio-cultural heritage and development..
