Are there any words in the comparative form that end y where you do not drop and add i?

You are correct! The rule of dropping the "y" and adding "i" before "er" in comparative adjectives only applies if the "y" is preceded by a consonant.

Here are some examples of comparative adjectives that end in "y" where the "y" is not dropped and "i" is not added:

* happy - happier

* funny - funnier

* busy - busier

* pretty - prettier

* ugly - uglier

Let me know if you have any other questions!
