The word join originated from the Old French word joindre around the 13th century. It was derived from the Latin word iungere, meaning to bind together. Over time, join evolved to mean to connect or unite and subsequently to become a member of or to participate in.
The word in has a much older origin from the Old English word innan. Its ancestral roots can be traced back to the Proto-Germanic word innana, which implies inside or within.
When combined, join and in form the phrase join in, which essentially means to participate or engage in an activity, discussion, or event with others.
