What is the meaning of prefix -sion?

The prefix "-sion" is a common suffix in English, not a prefix. It typically indicates an action, state, or process. It often comes from Latin words ending in "-sio" or "-sionem".

Here are some examples:

* Adhesion: The act of sticking or clinging to something.

* Decision: The act of making a choice.

* Confession: The act of admitting to a wrongdoing.

* Tension: A state of mental or emotional strain.

* Revision: The act of reviewing and improving something.

It's important to note that "-sion" is not the only suffix that can indicate action, state, or process. Others include "-tion," "-ment," "-ence," and "-ance".
