What is a suffix?
Suffixes are little groups of letters added to the end of a word like -ment, -ness, -ous, etc.
The suffix -ous means 'full of'.
When we add the suffix -ous to a noun it turns it into an adjective.
The word courageous means full of courage.
There are a few rules to know when adding the suffix -ous.
Rule 1: when adding -ous to words ending in 'e', the 'e' is dropped.
Example: adventure + ous = adventurous
Rule 2: when adding -ous to words ending in 'y', the 'y' is changed to an 'i'.
Example: fury + ous = furious
Rule 3: when adding -ous to words ending in 'our', our becomes 'or'.
