<u>-ed only</u>: label, wait, stay, explain, fail, prefer
<u>- d only:</u> care, like, agree, use
<u>double consonant +- ed
</u>: stop, jog, clap, hop
Explanation:
We form regular Past Simple verb forms by adding the termination <em>-ed </em>to the infinitive of the verb.
e.g. wait, stay, explain
However, there are some exceptions, as the result of the spelling rules.
If the verb ends in <em>-e</em>, we will add the termination <em>-d</em>:
e.g. care, like, use
If the verb ends in a vowel and a consonant, we double the consonant before <em>-ed</em>:
eg. stop, clap, hop
If the verb ends in consonant and <em>-y</em>, we take off the y and add <em>-ied</em>.
e.g. cry, enjoy, marry
