OP, the grammar of your original question is in question. Should you want to assert that it is indeed spelled 'definitely,' but with the added emphasis of 'fucking,' it really should be expressed: 'It fucking is spelled definitely...'. As 'It is fucking spelled definitely' implies the object of the sentence, 'it', is committing a lewd act upon spelled, and you confirm this absolutely ('definitely').
I feel shame that I have been compelled to write this.
