Mark:
Writing “which I responded to here” instead of “to which I responded here”
would not involve you in having dangled a participle, nor even in the lesser
syntactical crime — actually, pseudo-crime — of having ended a sentence
with a preposition. I refer you to Fowler’s entry headed “unattached
participles,” or (better, for my money) Follett’s headed “danglers.”
(Though you must then proceed straight through to read the following
article: “danglers, acceptable.”
Which reminds me of a Wodehouse moment I had many years ago. I was
attending a full-dress military event in a north of England town. The star
of the thing was a much-decorated elderly Brigadier, who came up from
Aldershot on the train. It had been arranged that he would stay overnight
at the home of my C.O., a Colonel, with a very prim and proper wife. The
Brigadier duly arrived at the house, parked his bags in the hall, and went
off to his bedroom to get kitted up for the event. This, for reasons I
forget, involved him pinning on his actual medals, a thing not easy to do
when you’ve already got your jacket on. A few minutes later, the downstairs
company was treated to the sight of this old soldier leaning over the
upstairs balcony, calling down to the Colonel’s wife: “Would you mind
coming up to the bedroom, my dear? I need help with my danglers.”
