When a commenter ripped one of my posts as being «larded with stilted turns of phrase and grammatical errors,» he was incorrect about the grammar part (
a trained grammarian, without my prompting, reviewed my post and found only one questionable prepositional choice) but was certainly entitled to his opinion about my writing style.
This doesn't mean writers are required to get degrees in philology or etymology or be
grammarians (though a little knowledge of all these fields helps); rather, it is the interest in and attention to words and sentences, to how we communicate by these means, that sets writers apart from, say,
train engineers.
