I want to know the answer to the following question:
What Greek word is -logy derived from?
All the background I'm provided with is that "The word phonology comes from the Greek φωνή, phōnḗ, "voice, sound," and the suffix -logy (which is from Greek λόγος, lógos, "word, speech, subject of discussion").". Is that enough to answer the question?
Answer: yes
