You want to add the suffix ed to the following words which word would require you to change the y to an i?

Betray, destroy, and obey do not need to be changed to add the suffix -ed, because the "y" at the end of each word is preceded by a vowel  (so  they would be spelled  "betrayed," "destroyed," and "obeyed").

but hurry is different; it has to  be spelled "hurried" because the "y" at the end of "hurry" is preceded by a consonant.

Example :
when you have one it's family,but when you have two it's families.

Ion know the answer so i just type more than 20 letter so i can get points to ask questions to write down on my homework
