Participative or participatory
What adjective can I use to describe a person who likes taking part in events or activities? I thought that participative was a good alternative, but I realized that participatory could be also posible. Then I looked up for their meanings and I got more confused. These were what I found:
Participative: relating to or involving participation; especially : of, relating to, or being a style of management in which subordinates participate in decision making.
Participatory: characterized by or involving participation; especially : providing the opportunity for individual participation

Answer

Oh wow - awesome question.  As a heads up, I haven't heard either word used with frequency. To my understanding, for a person who participates with frequency (and well, ie.  They are engaged.), it's better to use participative.

Participatory is more of the *ability* for a person to be participative.  (ie.  if a meeting allows participation, it would be a participatory meeting).

Hopefully, this answers your question!
