What does the suffix word ios mean in gracious mean?

The suffix "-ious" in the word "gracious" doesn't mean anything on its own. It's part of a larger suffix called "-ious", which is used to form adjectives from nouns or verbs.

Here's how it works:

* -ious indicates a state or quality.

* Gracious comes from the noun "grace".

* Therefore, "gracious" means "having or showing grace"

So, the suffix "-ious" helps form the word "gracious" and contributes to its meaning, but it doesn't have a separate independent meaning.
