Adding -y

Adding y to a word creates an “adjective“, which is a word used to describe something:

        The lazy dog, or
        The muddy dog

The words lazy and muddy tell us more about the dog.


By the way:
Adjectives don’t have to end in y, for example:   The quick dog, the green dog




Normally, all you need to do is add the -y to create a new word:

        crisp+ y >>> crispy
        cheek+ y >>> cheeky
        smell+ y >>> smelly


If the word ends with a short vowel (link), then the last letter is usually doubled
 
        fur+ y >>> furry
        fun+ y >>> funny
        hair+ y >>> hairy


If the word ends with an e, then drop the e

        grease+ y >>> greasy
        laze+ y >>> lazy


Note, these 'rules' also apply to longer words ending in a short vowel sound:
  
        careful+ y >>> carefully

Test: Add -y to the following words:
shade rose nut mud
sun rain cheek thirst
