Participate to

Yesterday a French colleague said he was going to “participate to a project”, instead of “participate in a project”.

Unfortunately, à in French can be, depending on context, either at, in, or to, and probably others. Here, the colleague chose wrong 🙂

I think I must make the corresponding error all the time. That is, I should be saying “participer à une réunion”, and I’d be willing to bet that I’ve said “participer dans une réunion” instead…
