This is the -s and -es sounds
When we add -s or -es to the end of a verb, it changes the word into the present tense
There is a simple rule to know whether to add -s or -es
If the base word ends in ch, sh, s, x or z, then you need to add -es
If the base word ends in anything else, then you need to add -s
The tricky part comes when you have a word like hope, this word does not end in ch, sh, s, x, or z, so we only need to add -s
However, the word hopes looks like we have added -es. It is important to note that here, we have only added -s because the e was from the base word.
