I want to know the answer to the following question:
What is the literal meaning of "healer?"
All the background I'm provided with is that "In Apollo's role as a healer, his appellations included Acesius (/əˈsiːʒəs/ ə-SEE-zhəs; Ἀκέσιος, Akesios, from ἄκεσις, "healing"), Acestor (/əˈsɛstər/ ə-SES-tər; Ἀκέστωρ, Akestōr, literally "healer"), Paean (/ˈpiːən/ PEE-ən; Παιάν, Paiān, from παίειν, "to touch"),[citation needed] and Iatrus (/aɪˈætrəs/ eye-AT-rəs; Ἰατρός, Iātros, literally "physician").". Is that enough to answer the question?
Answer: yes
