In the SMCR model of communication, what does 'S' stand for?

In the SMCR model of communication, which was developed by David Berlo, 'S' stands for 'Sender.' This model outlines the communication process by breaking it down into four components: Sender, Message, Channel, and Receiver. The 'Sender' is the individual or entity that originates the message and is responsible for encoding it in a way that can be understood by the Receiver. Understanding the role of the Sender is crucial, as it impacts how effectively the message is communicated based on the sender's experiences, attitudes, and skills. In this context, a clear identification of the Sender allows for a better understanding of how messages are formed and the intentions behind them, ultimately shaping the overall communication process.
