Student or Learner
I would appreciate if you could tell me the correct preposition for event. "At this event" or "In this event"?
The complete sentence is "At this event we launched “Be Effective” campaign to help improving knowledge of diabetic children by providing them with diabetes training courses."
***** NOT A TEACHER *****
Those two little words drive me crazy, too.
Occasionally they are interchangeable: "When I visit Paris next year, I'll stay at / in an upscale [expensive!] hotel."
Usually, however, I have found that native speakers prefer "at" when the emphasis is on the location.
In your sentence, the idea seems to be something like: At this location, we launched the "Be Effective" campaign to help diabetic children better understand how to manage their condition.
Now look at this sentence that I found in the "books" section of Google: "The data will usually include people and things involved in the event." I think that you can notice the difference. This time, the emphasis is on the event or occasion.
Finally, I like these examples from Webster's New International Dictionary / 2nd edition / Unabridged (1959):
To meet a friend at the library (a location or point).
To look for a book in the library (the interior is prominent [emphasized]).
