Definition of the word join in

The origin of the phrase "join in" can be traced back to the Middle English period, around the 14th century. The word "join" in these times meant "to come or go together" or "to unite", and it was often used in the context of religious events or ceremonies, referring to the congregation joining in prayer or singing hymns. The verb "join" evolved over time, taking on the meaning of "to participate or become involved in an activity" by the 16th century. This meaning is now commonly used in modern English, where "join in" is frequently used to invite someone to participate in an ongoing activity, such as a conversation, game or performance. The phrase "join in" gained popular usage as a way to not only include others but also to emphasise the communal and collaborative nature of the activity. It suggests equality and unity among participants and encourages a sense of willingness and openness to new experiences. In summary, the origin of the phrase "join in" lies in the historical meaning of the word "join" to unite and participate in activities, evolving over time to become a common expression that invites others to join in ongoing activities, promoting social cohesion and community engagement.
