ll - Free On-line Dictionary of Computing (26 May 2007) :

  LL
  
     <grammar> A class of language grammars, which can
     be parsed without backtracking.  The first L stands for
     Left-to-right scan, the second for Leftmost derivation.
  
     Often found in the form LL(k) where k is the number of
     tokens of look-ahead required when parsing a sentence of
     the language.  In particular, LL(1) is a fairly restrictive
     class of grammar, but allows simple top-down parsing
     (e.g. recursive-descent) to be used without wasteful
     backtracking.  A number of programming languages are LL(1)
     (or close).
