1. If the "y" is preceded by a consonant:
* Change the "y" to "i" and add "es".
* Example: baby -> babies, fly -> flies, story -> stories
2. If the "y" is preceded by a vowel:
* Simply add an "s".
* Example: boy -> boys, toy -> toys, day -> days
Here are some exceptions:
* Proper nouns: If the word is a proper noun, you typically just add an "s" even if the "y" is preceded by a consonant.
* Example: Mary -> Marys, Henry -> Henrys
* Words ending in "quy": These words usually add an "s" to form the plural.
* Example: attorney -> attorneys
