Here's how it works:
* It's usually added to nouns or adjectives to create adjectives.
* For example: "courage" (noun) becomes "courageous" (adjective).
* "danger" (noun) becomes "dangerous" (adjective).
* It describes a characteristic or quality.
* "A dangerous situation" means a situation full of danger.
* "A courageous act" means an act that shows courage.
Examples:
* Famous: Full of fame
* Humorous: Full of humor
* Nervous: Full of nerves
* Victorious: Full of victory
* Fabulous: Having the quality of being fabulous
Exceptions:
While "-ous" generally indicates "full of" or "having the quality of", there are some words where the meaning is slightly different. For example:
* Gaseous: Refers to a substance in the form of a gas.
* Pitiful: Expressing pity or sympathy.
It's always helpful to check a dictionary if you are unsure of the exact meaning of a word ending in "-ous."
