What is the rule for adding ing to a word ending in consonant and vowel such as skating?

The rule for adding "-ing" to words ending in a consonant and vowel is actually quite simple:

You just add "-ing" directly to the word.

For example:

* skate + ing = skating

* bake + ing = baking

* ride + ing = riding

This rule applies even if the final vowel is followed by a silent "e". This is because the "e" is dropped before adding "-ing".

For example:

* write + ing = writing

* hope + ing = hoping

Important Note: This rule only applies when the word ends in a single vowel followed by a consonant. If the word ends in two vowels or two consonants, you need to follow other spelling rules.
