This volume presents in-depth linguistic analyses of some Philippine languages—namely, Tagalog and South Sorsogon—focusing on morphology, syntax, and verb structures. Consuelo J. Paz provides a comprehensive study of Tagalog nouns and adjectives, detailing their morphological forms, syntactic functions, and phonological variations. Remedios M. Cayari examines Tagalog time adverbs, classifying them based on their structural forms—words, phrases, or clauses—and their grammatical functions. Antonio H. Escalante explores the verbal system of South Sorsogon, analyzing its verb morphology, inflectional patterns, and grammatical distinctions. Collectively, these studies contribute to a deeper understanding of Philippine linguistic structures, shedding light on their complexity and regional variations.
