What is the rule for applying suffixes to words ending in Y when preceded by a consonant?

Here's the rule for applying suffixes to words ending in "Y" preceded by a consonant:

1. Change the "Y" to "I" and add the suffix.

Example:

* happy + -er = happier

* cry + -ing = crying

* dry + -ness = dryness

Exceptions:

* If the suffix begins with "i" (e.g., -ing, -ish), keep the "Y" and add the suffix.

* Example:

* try + -ing = trying

* baby + -ish = babyish

Important Note: This rule applies only when the "Y" is preceded by a consonant. If the "Y" is preceded by a vowel, the "Y" remains unchanged.

Example:

* play + -ing = playing

* day + -s = days
