What does the prefix ous mean?

The prefix "ous" typically indicates "having the quality of" or "full of". It's often used to form adjectives from nouns.

Here are some examples:

* Dangerous: "Having the quality of danger."

* Courageous: "Full of courage."

* Fabulous: "Having the quality of being fabulous."

* Curious: "Full of curiosity."

* Numerous: "Having the quality of being many in number."

It's important to note that "ous" is not always the only way to create an adjective from a noun. Sometimes, "ful" or "ic" are used instead.
