Is biography a suffixs or prefix?

"Biography" is neither a suffix nor a prefix. It's a complete word on its own, meaning "the written account of someone's life."

Here's how to understand:

* Suffixes are added to the end of a word to change its meaning or grammatical function (e.g., "-ing", "-ly", "-ness").

* Prefixes are added to the beginning of a word to change its meaning (e.g., "un-", "re-", "pre-").

"Biography" is formed from the Greek words "bios" (life) and "graphein" (to write).
