Correct spelling


Correct spelling, explanation: because the word writer comes from the verb write and was created by adding the suffix -er (in this case -r, since the word ends with e), it is spelled with one t. Otherwise, we would have to change something within the core word. Therefore form writter is a mistake and writer is the correct word.

Definition of writer:
noun, a person who writes; an author of a particular piece of written work
John Green is an American writer, famous for young adult novels.
Jane is a teacher and her husband is a writer.

Incorrect spelling


Incorrect spelling, explanation: this form is incorrect because there is no need to interfere with the core of this word (write). We added -er to this verb (and received the word writer) as this suffix gives the word meaning of a person who does a particular thing. Therefore writer is the correct form here, and writter is mistaken.
