* Prefix: con-
* Suffix: -ing
Here's a breakdown:
* con- is a prefix that often means "with," "together," or "completely."
* -ing is a suffix that forms the present participle of a verb, indicating an ongoing action.
However, it's important to note that "descend" is the root word of "condescending" and not a separate prefix. The prefix "con-" modifies the meaning of "descend" to convey the idea of "looking down upon" or "treating someone as inferior."
