I want to know the answer to the following question:
Earlier Greek was represented by what?
All the background I'm provided with is that "tʰ kʰ/. Earlier Greek, represented by Mycenaean Greek, likely had a labialized velar aspirated stop /kʷʰ/, which later became labial, coronal, or velar depending on dialect and phonetic environment.". Is that enough to answer the question?
Answer: yes
