In this section, we will look at an important spelling rule for words that end in a consonant followed by y. When you add a suffix to these words, you should change the y to i, unless the suffix starts with an i.
Knowing when to change y to i will improve your spelling. For instance, the word happy changes to happiest when you add -est. You will also change study to studies and beauty to beautiful using this rule.
By learning this rule, you will feel more confident in your spelling. As you go through the examples, you will see how these changes work with different words, helping you understand this key part of English spelling.
