Usage of "be involved on"

1/ Is “be involved on” right or wrong?

So as not to forget the date of the meeting, I’ve made a note of it in my calendar
=> This is one of the test questions on Many apologies I no longer remember the exact sentence, but that is nearly correct. What I want to ask is: why can’t we use calendar here?
According to this following definition from, the option “calendar” seems fine:

cal·en·dar (kln-dr)

  1. Any of various systems of reckoning time in which the beginning, length, and divisions of a year are defined.
  2. A table showing the months, weeks, and days in at least one specific year.
    3. A schedule of events.
  3. An ordered list of matters to be considered: a calendar of court cases; the bills on a legislative calendar.

Hi Nessie

Haven’t you already asked about ‘be involved on’?
Generally speaking, ‘be involved in’ is the commonly used phrase.

To evaluate a possible use of ‘be involved on’, you would have to post a complete sentence.

I would say that I made a note about the time and date of a meeting
[i]- on my calendar

  • in my appointment book
  • in my time planner[/i]

And I think the Brits might still be saying

  • in my diary

Hi Amy,
Sorry for the matter of “be involved on”. You know, I have so many queries that I can’t remember which I have asked and which I haven’t (+_+)
Here is the use of “be involved on” in a complete context. please check if it is possible to use the phrase here:
Hundreds of scientists have been involved on the research
=> this is a mistake correcting excercise and I think “be involved on” here is wrong, just because I often just see people use “be involved in”, but my teacher said it was ok, and the mistake here is “have been involved”. She claimed that it shouldn’t be in passive voice here

Hi Nessie

“Hundreds of scientists have been involved in the research.” = Some of those scientists may have stopped their research in the meantime, and the rest are probably still involved.

“Hundreds of scientists are involved in the research” = This is a statement of current fact. In other words, all of the “hundreds” are currently involved.

Thanks Amy,
but could you please tell me some cases in which “be involved on” is used? (correctly and formally) or is it just used in spoken and non-standard English?

Sorry for being so fussy
Many thanks once again

Hi Nessie

I’d use “be involved in”. The only possible justification I can think of for using ‘on’ would be if “be involved” were somehow parsed separately from “on” in a sentence.
