Incorrect spelling


Incorrect spelling, explanation: we do not double t in writer because t isn’t the last letter in the core word write. Therefore we have no reason to think about doubling this consonant, since e is the last letter in the word we are adding a suffix, so writter is incorrect. The correct form is writer = write + -er.

Correct spelling


Correct spelling, explanation: writer is the correct form of this noun. This is due to the fact, that it is made from the verb write, there is no reason to double consonant t (as it’s not the last letter in the word). In this case suffix -er was added; because of e being the last letter in write, it was skipped in the suffix, hence writer.
