What is the prefix and suffix of word postdoctorate?

The word "postdoctorate" is a bit tricky because it's not formed with traditional prefixes and suffixes. Here's why:

* "Post" is considered a prefix, but it's usually used to denote "after" or "following" something. Here, it indicates the stage *following* a doctorate.

* "Doctorate" is the root word and is not a suffix in this case.

So, while "post" is technically a prefix, the word "postdoctorate" is a compound word, formed by combining "post" and "doctorate."
