REPL stands for read-eval-print-loop, or just an interactive session (usually in your terminal), where you can enter some expression and immediately evaluate it, seeing the result. After evaluating, the whole flow repeats, and it works until you exit the process. So, R stands for reading your command, E stands for evaluating it, P stands for printing the result of the execution, and L means to run the whole process again, “in the loop”.
