As it says in the headline, looking for a word that represents "the art of writing" in the same way that 'oratory' in some sense represents the "the art of speaking".
She had great _______.
BONUS: Obviously a noun, but is there a specific grammatical term for words like these? If so, what is it?
The poor example above has caused unnecessary confusion because a noun doesn't fit the sentence. Have left unchanged so responses still make sense.
His oratory was legendary. Her _______ was legendary.
