Klong
Klong is a language based on K (probably K3) which removes K's syntactic ambiguity and much of its overloading by using more digraphs (primitives composed of two characters) to separate extra meanings. The removal of syntactic ambiguity means Klong has a context-free grammar.
Primitives
Klong documentation refers to primitive functions ("verbs" in K) as "operators".
