A shell variable is a temporary location in memory that can be used to store and retrieve information.
For example, the following creates a shell variable and then prints it out:
stuff="Hi there"
echo $stuff
will echo out 'Hi There' to the screen. It has the words "Hi There" saved in a memory location called $stuff, which can be retrieved by its name.
