Answer:
D. Where: Greek
Why borrowed: There is a trend in English to use Greek words in psychology.
Plural form: psychoses
Why: To form the plural of Greek words ending in -sis, change to -ses.
Explanation:
This is the correct origin of the word "psychosis." The word comes from the Greek. We can tell this by the fact that the word uses the prefix psyche, which is the Greek word for "mind" and is found in other words such as psychedelic. This is one example of a larger trend in English to use Greek words in psychology. In order to create the plural of this word, we need to change the ending "-sis" to "-ses."
