Correct spelling


Correct spelling, explanation: blamed is a past tense of the verb to blame. Just like in the case of most regular past tense forms, the derivation is simple and it’s just based on adding -ed suffix. In the case of blamed and other words which base form ends in e, only -d is added to form a past tense.

Incorrect spelling


Incorrect spelling, explanation: the form blaimed is incorrect and does not exist, because there is no base word to correspond to it. Blaimed would require a verb to blaim, but there is no such word in English vocabulary. Pronunciation of blamed may lead someone to this word, but it does not function in English.
