Morphosyntax
Morphosyntax refers to the study of the structure and formation of words and phrases in a language, including how words are modified to indicate tense, aspect, mood, number, gender, case, and other grammatical categories. It explores the relationship between morphology (the study of the internal structure of words) and syntax (the study of how words are combined to form sentences), focusing on how these elements work together to convey meaning in communication.
