Which branch of linguistics analyzes the formation of the word ‘unbelievable’ from morphemes?

💡 Explanation:

Morphology is the study of the internal structure of words and the rules by which words are formed, primarily through the combination of morphemes (the smallest meaningful units). In 'unbelievable,' the morphemes are 'un-,' 'believe,' and '-able.' Syntax deals with sentence structure; Semantics deals with meaning; and Phonology deals with sound systems.
