Today is National Grammar Day in the US, and to mark the occasion we’re visiting some of the best grammar blogs on the web. This doesn’t claim to be a comprehensive list, and “best” used to describe a blog is about as vague and subjective as the laws of grammar and language are in guiding the ways we write and speak — not to mention the way we interpret, police and abide by those laws, and the way we write about them. Just as there’s an infinite variety of commentary about what goes into our mouths that is about as diverse as the culinary fare it describes, so there’s a seemingly endless choice of writers — and writings — about what comes out of our mouths. Whether delivered by an expert or a casual observer, presented as a serious study or thrown into cyberspace as a lighthearted jab, whether complaining or rejoicing, teaching or deriding, assuming airs and graces or slumming it with slang, citing the historical linguists or poking fun at the greengrocer’s apostrophe, grammar blogs come in all shapes and sizes.  Witty, serious, provocative, instructive, academic, thought-provoking, enlightening, irreverent — and any combination of the above, there’s something to suit every mood and taste. But what they all have in common — and what presumably motivates anyone who bothers to devote any time to writing about grammar — is a profound and fiercely protective love of our mother tongue. Like parents of teenagers, we try hard to exercise restraint, tolerance and good humor in the face of broken rules and astonishingly bad behavior; to set boundaries that we know will be pushed, resisted and ignored; and to pick our battles carefully. But at the end of the day we’re brimming with love, pride and awe as we watch our children evolve into adults, and this is how we feel about our language as we watch it bend and adapt to the changing needs of the mouths and keyboards it serves: we love it dearly, unconditionally, and that’s why we write about it.

Here are some of Glossophilia’s favorite blogs, in no particular order, with the blogs’ own short descriptions and author bios where available, and a note on their general ‘vibe’. (Note: I would describe most, if not all, of the blogs here as geeky — and I mean that as a compliment. It seems to be a requisite quality of any good grammar blog. And blogs with words like n-gram tagged in 64-point type don’t qualify for this list: sorry!) Please tell us about any other great grammar blogs out there.
