There has been much heated discussion here on the desirability of editors using style guides when reviewing stories.
I am obviously only intending to use guides in accordance with authors' wishes.
After a (not yet very detailed) look at a style guide that generates extreme hostility (CMoS), I have only one serious reservation about using it.
I see numerous examples of this, but my only reservation is its implied dictate, "Thou shalt only use words as forms of speech included in dictionary definitions".
Two examples are dictionary definitions of 'like' and 'based (on)' state they are only adjectives, but in everyday usage they are frequently used in other ways.
'Like' is being used as a conjunction in, "It is that way, like it should be." 'Based on' is being used as an adverb in "(Something) is adjusted based on (some method)".
I see no reason to resist the inventiveness of speakers in using words as forms of speech other than their dictionary definition.
In contrast, I am comfortable adhering to dictates for the preferred preposition to use with verbs.
I have no problems following other things in a style guide, including the use of hyphens and capitals, how to abbreviate words, and when to use words for numbers. Consistency in using whatever style is chosen seems important, and I cannot see how to achieve that without using some style guide.
For punctuation I am struggling to find an approach suitable for fiction authors. There does seem to be many situations where commas are required in formal writing, but should be treated as optional by fictional authors. Apart from that, I have no problems following what various guides define as correct uses of punctuation.
I would appreciate comments about any other instances where authors feel that the dictates of guides are unsuitable for authors of fiction.
