Shone.

Well, there are lots of grammar blogs that take the commenter's side, at least as far as shined/shone.

Shone.

I've always thought of it as "the light shone over the city" shone being the past tense of shine in the emitting light sense. "The man shined his shoes before going to bed" with shined being the past tense of shine as in polishing something. I find that common usage has over the last 20 years or so moved to shined as the past tense in the emitting light sense and I find I am using it that way myself.

Shoney's (shiny!)

I am so sorry.

Even though Germany finally drops 20 rules for the the umlat or verb tenses or something, I'd like to note that ending sentences on a preposition is all well and good but this is a freaking abomination.

Shone.

I would totally use "shone" there, but I'm not SUPER confident in my choice.

For what it's worth, I have also retired the term "grammar nazi" in favour of the term "grammar aficionado" because I think it's high time we stopped trivializing the suffering levied by the Nazis by tossing that word around. Just a suggestion.

I also have a REALLY hard time spelling aficionado.

Hmmm. "Aficionado" doesn't quite do it for me, it's not crazy enough. What would be better? Nut? Supernerd? Police might work.

Grammar Hammer, surely.

Grammar hammer is GOOD. And, I can appreciate that aficionado lacks a certain ZEAL.

Grammar Hammer sounds like the moniker for a nerdy wrestler and I love it.

I'm not sure things like nazis and Hitler can be trivialized in Western culture at this point, that's why they're invoked as a form of transgressive humour, unless you're saying people don't know what they refer to any more and everything is all considered different versions of dick now... which really pisses me off in so many ways, not the least of which is the waste of comedy in the great dumbening.

Oh, man, now I am pissed. Stupid people ruin everything.

Yes! Grammar Hammer!

"Shone!" the Grammar Hammer announced, in clanging tones.

Shone, I'd use it, but...it's an irregular past tense and the language is moving away from that in the interest of simplification, so I wouldn't sweat it. Us poetic types can read our Longfellow and Shakespeare and King James and enjoy it forever.

I'm over Nazi-dom, so now I revert to frameworks. What's the style sheet? If the Globe's style sheet says "Shined," then great, shined it is. My personal style sheet would not endorse it, but that isn't relevant to the Globe. So I guess this means I'm a grammar relativist, and I'm fine with that. As I age I make my peace with my inability to enforce absolutes and control expressions.
