Answer:
Latin
Step-by-step explanation:
The primary basis for medical terminology is Latin along with Greek. We can even see such an example in the phrase "medical terminology" itself
Starting with the latter, the root phrase "-ology" comes from the Greek meaning "the study of a subject or field", and "termin-" from Latin meaning "word or term".
The root phrase "medico-" comes from the Latin word medicus meaning healing or physician. The phrase "-al" at the end of the word "medical" comes from the Latin phrase -alis, which is one of a handful of phrases from the language that means "pertaining to."
Put it all together, the phrase medical terminology's Latin-derived definition is "the study of words pertaining to healing" perfectly describing terms of medical science!
