LC: To use suffixes to understand the meaning of words.
A suffix is a letter or a group of letters that can be added to a word to change its meaning.
'Dangerous' means 'full of danger'.
'Adventure' becomes 'adventurous'.
'Fury' becomes 'furious'.
'Humour' becomes 'humorous'.
Sometimes you can clearly tell what the root word is so we follow the usual rules for adding suffixes beginning with vowel letters.
Adding Suffixes Beginning with Vowel letters
The -e at the end of a root word is dropped before adding any suffix beginning with a vowel letter.
Carnivore + ous = carnivorous
When a word ends with a vowel and y keep the y.
joy + ous = joyous
When a word ends in a consonant and y, change the y to i before the suffix -ous is added.
victory + ous = victorious
If none of the other rules apply we just add -ous onto the ending.
poison + ous = poisonous
Suffixes are letters that can be added to the end of words to change their meaning.
'nice' becomes 'nicely'
'happy' becomes 'happily'
'terrible' becomes 'terribly'
Add the correct suffixes to these words and put them into the correct column.
