Incorrect spelling, explanation: some English users may think that it’s enough to add the -ed ending to the word’s base in order to create a past simple/past participle form. Most often it’s true. However, sometimes we also have to double the last consonant – when there is a single, stressed vowel before it. This rule explains why stoped is a misspelling and stopped is the right version.

Correct spelling, explanation: the word stopped is a derivative of the verb stop. As you can see, it contains a double -p letter. If you’re wondering why, here’s the crucial rule: we need to double the final letter when a one-syllable verb ends in consonant + vowel + consonant. Therefore, stoped is not correct.

Definition of stopped:
verb, put an end to something
Sophie stopped eating when she found herself fat.
My uncle said that he never stopped loving my aunt.
