It's a language element of Scheme indicating that the identifier is an identifier, which in Scheme is called a "symbol". Strings in Scheme are surrounded with double quotes: "a string". One can define a symbol to refer to a string: (define string "a string") and would afterwards use it with the leading single quote (print 'string).
