Correct spelling, explanation: overrode is a past tense form of the verb override. As you can see, it’s an irregular verb, because it has its own unique tense form. Although, this does not change the fact that the derivation must agree with the word-formation base, and the base contains a double -r consonant. It was created by combining the prefix over- and the verb ride. That’s why the only correct version is overrode, not overode.

Definition of overrode:

Incorrect spelling, explanation: you shouldn’t spell this word as overode because this version lacks one -r letter. The correct form – overrode – consists of two elements: the prefix over- and the past tense of ride (rode). This mistake is often made by English speakers because two -r consonants next to each other seem unnatural. However, it must be remembered that each of them is contained in separate elements of the word overrode.
