What prefix is for the word payment?

There isn't a specific prefix for the word "payment" in the way that you might think of a prefix for a word like "pre-payment."

The word "payment" itself is already a complete word and doesn't typically have a prefix added to it.

However, you can use prefixes with related words:

* Pre-payment: A payment made in advance.

* Over-payment: A payment that is more than the amount owed.

* Under-payment: A payment that is less than the amount owed.

Let me know if you had a specific prefix in mind, and I'll do my best to help!
