In the term morphology, what does 'logy' denote?

The term "morphology" is derived from Greek, where the suffix "logy" comes from the word "logia," which means "the study of." In the context of morphology, it specifically refers to the study of the structure and formation of words in a language, including how roots, prefixes, and suffixes come together to create meanings. This understanding of "logy" emphasizes its role in denoting an academic or systematic study of a particular subject.

In contrast, other options like "shape," "meaning," and "form" refer to specific elements related to the overall morphology but do not capture the broader implication of study or discipline that "logy" conveys.
