There aren't a lot of symbols to Lisp but there's plenty of syntax

Using Racket:

  (if bool then else) instead of (if bool then) or (if (bool then) (bool else))
  (if (> x y)
    (x)
    (y)) ;fails for numbers because (x) is considered a function call (even though 3 is an invalid identifier and thus can be assumed to be always be a number).
 (define (fun x y) (...)) instead of (define fun (x y) (...)) or (define ((fun (x y)) (...)))

That's syntax.

Just because I'm not using {}'s here and infix there doesn't make it any less syntax. That's just the two most basic forms too; bring in loop? forget about it. This also ignores things like '(@,) or (x . y) but I'm not a lisper so I don't know how often that actually comes up
